Indications for magnetic resonance imaging of the spleen

MRI is deservedly included in the group of the most informative and safe diagnostic techniques. However, there are still contraindications to MRI and are associated with the use of electromagnetic radiation in the research process.

Limitations to tomography must be taken into account by specialists when prescribing the procedure and by the patient during the preparatory stage.

Briefly about the MRI technique and indications

The principle of MRI is nuclear magnetic resonance, which began to be actively used after the 70th year.

The diagnostic procedure has gained popularity thanks to modern equipment - tomographs, which help identify minor pathologies of organs and tissues at the initial stage of their development.

MRI

If at the beginning of the use of MRI it was used to identify pathological processes in the brain, now MRI is prescribed to study a large number of organs, especially with the use of a contrast agent.

Possible indications for MRI diagnostics:

Type of procedureIndications

MRI of the brain	- neoplasms - stroke - suspicion of the presence of an aneurysm - structural anomalies - head injuries - eye and ear diseases
MRI of the pituitary gland	- migraines - disruptions in the menstrual cycle - disturbances in the functioning of the endocrine system
MRI of the sinuses	— allergic rhinitis — frequent headaches — pain in the tooth, cheekbones — chronic inflammation of the upper respiratory systems — suspicion of cancer
MRI of the thoracic region and mediastinum	- blood clots in the heart area - defects - oncology search - emphysema - pneumonia
Abdominal MRI	- suspicion of the development of oncology - congenital structural features of organs - trauma to the area - suspicion of the presence of foreign objects (with the exception of metal ones) - identification of the nature and stage of the developing pathology
MRI of the adrenal glands	- high or low blood pressure - active hair growth on a woman’s body and face - muscle weakness - sudden fluctuations in weight (of unclear nature) - enlarged mammary glands in a man
MRI of the pelvic organs	- organ injuries - infertility - congenital changes in the genitourinary system - severe pain in the local area - vaginal bleeding of unknown etiology in a woman - postoperative control
MRI of the spine	— injuries of the spinal column — chronic pathologies of the spine — suspicion of the development of oncology—herniated intervertebral discs

Why there may be restrictions on MRI diagnostics

During an MRI examination, the patient is exposed to a powerful electromagnetic field.

Hydrogen molecules in the tissues of the human body, under the influence of corresponding waves, change their direction.

Limitations of MRI

In some cases, the described process may be dangerous to the patient's health, even despite the absence of radiation exposure.

Before prescribing an MRI to a patient, the doctor interviews the patient to determine a list of possible limitations.

A person should be frank with a doctor, since the number of contraindications in the case of magnetic tomography is large. The entire set of restrictions is divided into two groups.

A set of absolute contraindications to MRI diagnostics

Absolute contraindications to MRI are a reason to search for an alternative type of diagnosis. Details about each of the restrictions are below.

The specialist will prohibit the patient from undergoing examination if the following metal objects are found on his body:

• parts of clothing (buttons, buttons, etc.);
• jewelry (brooch, earrings, etc.) that contain metal;
• hair care items (hairpins, hairpins);
• piercing;
• hearing aid;
• office;
• glasses.

Implants and electronic devices

MRI diagnostics cannot be performed on persons who have implants and electronic medical devices in their body:

• pacemaker;
• medical clips;
• metal spirals in vessels;
• heart valve;
• dentures and braces;
• pumps;
• cochlear implants;
• joint prostheses;
• nerve stimulants;
• surgical materials (pins, screws, etc.). Types of braces

Metal objects, implants and devices will result in distorted images. There is a possibility of harm to the patient's health.

Powerful electromagnetic radiation can move implants or slow down the operation of an electronic device.

Bullets and shrapnel

Among other metal objects, bullets and shrapnel may be found in the body. Under such circumstances, MRI diagnostics is also contraindicated for the patient.

These elements can affect the quality of the resulting images. Under the influence of a magnetic field, these elements will shift, which means they will cause severe pain to the patient or even lead to the death of the subject.

If it is not possible to remove the object, as in the case of a bullet or shrapnel, it is necessary to look for an alternative diagnostic method.

Possibility of an allergic reaction

One of the absolute limitations to MRI is an allergy to the contrast, which is used for the purpose of detailing the image.

The basic component of the product is gadolinium. It acts as an allergen. The risk of developing an undesirable reaction is small, however, in order to avoid making a mistake, the patient undergoes an allergy test to the drug.

If no adverse reactions occur, the person is sent for diagnostics. Otherwise, the doctor prescribes an adequate alternative.

People with kidney failure or suspected kidney disease are among the patients who should not have an MRI with contrast.

Group of relative contraindications to MRI

Relative contraindications to magnetic resonance imaging:

• claustrophobia (possible use of open-type equipment);
• the presence of non-ferromagnetic inner ear implants and other elements for medical purposes;
• the presence of tattoos containing metallic pigment (diagnosis is not excluded if the body pattern is localized outside the study area);
• mental disorders of the patient;
• first trimester of pregnancy and lactation;
• injuries accompanied by a serious human condition;
• the patient is overweight.

It’s worth taking a closer look at the four latest restrictions.

Mental disorders

• The procedure itself does not pose a danger to persons with mental disorders, however, nervousness, aggressive behavior, panic attacks, alcohol and drug intoxication are reasons for refusing diagnosis.
• The result of an MRI in this case may be a deterioration in the patient’s psycho-emotional behavior and poor-quality images.
• If the procedure cannot be canceled, the patient is asked to take sedatives.

Pregnancy and lactation period

Today, there is no direct evidence of the adverse effects of MRI diagnostics on the developing fetus.

Therefore, a woman expecting a child, from a theoretical point of view, can be examined at any period of pregnancy, except for the 1st trimester.

Things are different if magnetic tomography is performed using a contrast agent. The components of the product can negatively affect the child and cause the development of severe pathological processes in the baby’s body after birth.

The same reason becomes a reason for refusing MRI diagnostics to a woman who is breastfeeding. You can resume lactation a couple of days after the procedure.

Trauma and serious condition of the patient

Certain injuries, such as open fractures, limit the use of MRI. During the diagnostic process, the patient will have to remain motionless for a long period - pain and discomfort will not allow the patient to remain calm.

The result of such a study can be not only a poor-quality image, but also a deterioration in the patient’s condition.

If it is not possible to refuse the procedure, it is permissible to use an open-type MRI scanner to alleviate the discomfort of the person being examined.

Open type (C-shaped)

When the pain is intense and does not allow the patient to remain in one position, it is worth considering replacing MRI with an alternative type of diagnosis.

Obesity

1. It is not easy to make a diagnosis using MRI for a person weighing more than 120 kg: the equipment table is not designed for such a weight, and the patient will not be able to fit into the magnetic tunnel.

2. An additional reason for refusing an MRI diagnosis to an obese person is the low information content of the technique in the case of people diagnosed with obesity.
3. A solution in such circumstances may be to conduct a study in an open-type tomograph.

4. Some medical centers have specialized equipment designed for overweight people.
5. Magnetic resonance imaging is a diagnostic method that is characterized by an extensive list of limitations.
6. However, it is important to emphasize that all contraindications are objective and justified in order to preserve the health of the person being examined.
7. Before undergoing diagnostics, it is important to remain frank with the specialist and strictly follow the doctor’s recommendations when preparing for MRI diagnostics and during the scanning process.

MRI of the spleen

MRI of the spleen is a technique for obtaining layer-by-layer images of an organ by scanning the examination area with radiofrequency pulses in an electromagnetic field.

The list of instrumental studies of the spleen is quite limited (ultrasound, lienography, scintigraphy), among which MRI is the most accurate and preferred diagnostic method.

MRI allows one to judge the topography, morphological structure of the spleen, surrounding soft tissues and blood vessels and the presence of pathological processes in them.

MRI of the spleen is a highly informative tool for diagnosing organ malformations, traumatic injuries, splenomegaly, circulatory disorders, oncological processes, etc. The study is performed independently or as part of an MRI of the abdominal organs, and may require the introduction of MR contrast.

MRI of the spleen is a highly informative tool for diagnosing organ malformations, traumatic injuries, splenomegaly, circulatory disorders, oncological processes, etc. The study is performed independently or as part of an MRI of the abdominal organs, and may require the introduction of MR contrast.

MRI of the spleen has been used for diagnostic purposes relatively recently, with the advent of modern high-power tomographs. The accuracy of the imaging is determined by the response of protons in water atoms to electromagnetic radiation.

For this reason, the technique has maximum information content in relation to soft tissues rich in water. MRI of the spleen is used in the field of therapy, gastroenterology, hematology, and oncology.

The procedure is prescribed after a routine ultrasound of the spleen, which is a low-cost diagnostic method that allows you to assess the shape and size of the organ and generally study its internal structure.

The low resolution of ultrasound images does not make it possible to detect small formations, regardless of their nature. The identified structural changes are in many cases nonspecific, so a specialist can differentiate the process. MRI of the spleen allows you to diagnose tumors at the initial stage and cysts ranging in size from 10 mm.

Scanning is carried out in three planes, therefore it provides the opportunity to assess the relationship of formations to nearby structures, blood and lymphatic vessels.

MRI of the spleen is successfully used for the differential diagnosis of splenomegaly, while ultrasound does not always reveal the cause of organ enlargement.

It is important to understand that if any pathology of the spleen is suspected, ultrasound becomes the primary diagnostic method. However, the detected changes in many cases require confirmation, for which MRI of the spleen is prescribed.

The data obtained is used to plan conservative treatment and determine the scope of operations, and are also used in the postoperative period to monitor the effectiveness of therapy.

Indications

The range of indications for examination is very wide. The most common reason for prescribing MRI of the spleen is splenomegaly. Organ enlargement can be associated with inflammatory processes, injuries and tumors. Most pathologies of the spleen lead to its enlargement.

Scanning is required when ultrasound data is insufficiently accurate or incomplete. MRI of the spleen is used to confirm Gaucher disease and is also required in the diagnosis of portal hypertension caused by cirrhosis of the liver and other causes.

Anomalies in the development of the spleen are clearly visible in the photographs. In addition, examination is prescribed to identify benign hemangiomas and malignant tumors of the spleen.

The detected neoplasms may be metastases of neoplasia of another location; in this case, MRI of the spleen is of great importance in assessing the extent of the oncological process.

Hemorrhoids kill the patient in 79% of cases

The high accuracy of the study makes it possible to detect the morphological basis of hematological diseases: sickle cell anemia, leukemia, etc. The examination can be performed for typhoid fever and other inflammatory and infectious processes in the abdominal cavity.

Pain in the spleen area with radiation to the back is an indication for MRI of the spleen if ultrasound does not provide information explaining the patient’s complaints. Scanning is required if hemorrhagic rashes or elements not associated with injuries appear on the body.

At the stage of treatment, MRI of the spleen is prescribed to monitor the effectiveness of treatment, for example, after removal of a tumor or a course of therapy for leukemia.

Contraindications

An absolute contraindication to the examination is any metal elements in the patient’s body.

MRI of the spleen is not performed in the presence of complex electronic devices, such as an artificial pacemaker, neurostimulator, or hearing aid, since their operation may be disrupted in a magnetic field.

Contrast studies are not performed on patients with chronic renal failure and breastfeeding women. If a patient with an identified allergy has low information content of native MRI, it is preferable to choose another diagnostic procedure. MRI of the spleen in patients with epilepsy is performed under general anesthesia if absolutely necessary.

Preparing for MRI of the spleen

The patient is sent for examination by a therapist, hematologist or oncologist after a preliminary ultrasound and laboratory diagnosis of organ function. 1-2 days before the procedure, a diet excluding brown bread, legumes, cereals, dairy and other products that increase gas formation is indicated.

MRI of the spleen is performed 4-5 hours after eating. Activated charcoal is prescribed two hours before the scan, and an antispasmodic drug is taken an hour before the procedure. If an MRI of the spleen with contrast is planned, renal function is first assessed.

Allergy tests with a contrast agent are also performed.

Methodology

The tomograph is a hollow cylinder with magnetic rings. In the center of the tube is a couch on which the patient sits during the scan. The average duration of an MRI of the spleen is 30-40 minutes.

Some images are taken while holding your breath, which the radiologist reports via a two-way communication system. During the administration of contrast liquid (gadolinium and its compounds), the patient may feel warmth and heat in the body, dry mouth, and dizziness, which disappear within a few minutes.

Complications of MRI of the spleen are possible in the presence of metal elements in the body and in the case of chronic renal failure. Allergic reactions to gadolinium are extremely rare. The examination result is prepared within a few hours.

The patient receives images and a written report from the radiologist. Additionally, it is possible to record data on digital media.

Cost of MRI of the spleen in Moscow

The cost of scanning varies widely. If an examination with contrast is indicated, the cost may increase by 1.5-2 times depending on the patient’s body weight, since the required volume of contrast fluid is calculated per kilogram of weight.

The price is determined by the time of the examination; some clinics offer discounts on the procedure at night. The cost of MRI in Moscow is higher if the scan is performed on more expensive equipment with high power. In private clinics the procedure usually costs more.

The price partly depends on the qualifications of the radiologist and the availability of additional services.

MRI of the spleen: what does the examination show? examination of the spleen using magnetic resonance imaging examination of the spleen using magnetic resonance imaging

MRI of the spleen
is a method of examining the organs of the human body, thanks to which it is possible to obtain clear, detailed images of the spleen, surrounding tissues and organs, blood vessels and nerves without harm to the patient’s health.

Magnetic resonance imaging allows you to obtain layer-by-layer images of the organ under study. The thickness of the layers can range from several millimeters to 1 centimeter. The cutting plane can be vertical, horizontal and oblique. Thanks to this, using MRI it is possible to detect even small tumors and begin treatment in the early stages of the disease.

CT or MRI of the spleen?

Patients are often concerned about how informative the diagnosis of the spleen is using MRI compared to computed tomography. In fact, the diagnostic capabilities of both methods are approximately equal.

A clear advantage of MRI is the safety of the method and the ability to conduct studies as often as necessary, without any harm to the human body.

The disadvantage of MRI is the inability to examine patients in serious condition when, due to injury or illness, a person needs a cardiac monitor or a ventilator system.

What does an MRI of the spleen show?

Magnetic resonance imaging can reveal
:

1. congenital features of organ development;
2. change in the position of the organ (the so-called “wandering” spleen);
3. spleen injuries;
4. torsion of the pedicle of the spleen (compression of the neurovascular bundle of the spleen after the organ rotates around its axis);
5. circulatory disorders (infarction) of the spleen;
6. infectious processes in the spleen;
7. increase in size (splenomegaly);
8. cysts.

Most of the pathological changes listed above are visible on images taken during conventional MRI. The exceptions are tumors and some types of pathologically changed tissues that are not visible on photographs or have unclear outlines. In this case, an MRI of the spleen with contrast is performed.

Indications for examination

You can get a referral from your doctor for an MRI scan of the spleen in the following cases:
:

1. changes in skin color, the appearance of bruises and bruises, rashes;
2. severe pain in the left side, which radiates to the shoulder blade and shoulder;
3. splenic cysts or the appearance of symptoms indicating the likelihood of having cysts (a feeling of fullness in the left hypochondrium after eating, vomiting, a tingling sensation in the chest, cough, pain in the chest on the left);
4. suspected injury to the spleen (blow to the left hypochondrium, fracture of the ribs on the left, fall on the stomach, compression of the abdomen and lower chest, penetrating wounds);
5. violation of the patency of the vessels of the spleen (torsion of the legs, thrombosis, embolism);
6. spleen abscess;
7. tumors;
8. typhoid fever;
9. leukemia

Contraindications for MRI of the spleen

Magnetic resonance imaging is not performed in the following cases
:

1. there are metal foreign bodies in the patient’s body;
2. the patient has an implanted pacemaker or other electronic device;
3. the need to use a cardiac monitor to monitor the patient’s condition, a ventilator, etc.

Contraindications for administering contrast to a patient
:

1. chronic renal failure;
2. pregnancy at any stage and the entire period of breastfeeding;
3. intolerance to gadolinium-based drugs in the past.

Preparing for the examination

The spleen is located in the abdominal cavity, so the clarity of its images is affected by the condition of the intestines, the amount of gases and intestinal contents, and the activity of peristalsis. To make the examination more informative, it is necessary to prepare:

1. for 2 days do not eat foods that increase gas formation in the intestines (sweets, flour, legumes, cabbage, etc.);
2. on the day of the examination you will need to refuse to eat; you can drink water in the required quantities;
3. you can take enterosorbents (activated carbon or another drug as prescribed by your doctor);
4. 30 minutes before the start of the examination, take a No-shpa tablet.

If the examination is performed for emergency reasons, then no preparation is carried out
.

How is the examination carried out?

Before the procedure it is necessary
:

1. change into a loose and comfortable shirt or robe, which is offered by the medical staff, if the patient’s own clothing is tight and has metal fasteners and trim elements;
2. remove metal jewelry, remove earrings for piercing;
3. leave plastic bank cards, phones, tablets and other electronics in the locker room.

If an MRI of the spleen is planned to be performed with contrast enhancement, then a special catheter is installed in a vein in the patient’s arm, through which the contrast agent can enter the blood during the entire examination procedure.

The prepared patient is placed on the extendable table of the tomograph in a supine position. The table slides inside the device.

What is MRI with contrast? Magnetic resonance imaging: contraindications, indications - MK

Magnetic resonance imaging is considered a safe research method, since it does not expose the patient to radiation or ionizing radiation, and is therefore harmless to the body. MRI is prescribed for both adults and young children. As the name implies, this diagnostic method is based on the phenomenon of nuclear magnetic resonance.

To understand what an MRI is, you need to have an idea of ​​how it works. The essence of the technique is that the nuclei of some atoms placed in a magnetic field can absorb electromagnetic pulses. Subsequently, they convert the energy into radio signals and, at the end of the pulse, emit them. Oscillations can be registered by special devices.

Tomographs used in medicine work on the nuclei of hydrogen atoms that are part of water molecules, which makes up 70% of the human body. The amount of fluid in different organs of the body differs, as a result of which the tissues emit different signals during the scanning process. Thanks to this, the MRI machine can accurately:

• visualize internal organs;
• distinguish healthy cells from pathological ones;
• identify any organ dysfunction.

This is a unique diagnostic method that allows specialists to obtain high-quality images of almost all structures of the human body. An MRI examination visualizes soft tissues, joints, and cartilage particularly accurately and in detail.

The innovative technique allows doctors to make images of structures that are quite difficult to obtain with other research methods.

Such hard-to-reach tissues include those located near bone structures, for example:

• intervertebral discs;
• spinal cord and brain;
• inner ear;
• pelvic organs;
• ligamentous apparatus.

However, images of structures containing small amounts of water are less accurate. Therefore, magnetic resonance imaging is very rarely used to examine the lungs or skeletal bones.

Study with contrast

In order to obtain clearer images during the study, the patient is prescribed a special substance before starting the procedure. This diagnostic method is called MRI with contrast.

Many people wonder if this remedy could be dangerous for them. Such doubts are absolutely groundless, since contrast is just a dye that allows you to highlight and better visualize the structures of the body.

Its use does not pose any threat to the patient’s health, since the product:

• has no contraindications;
• quickly eliminated from the body;
• does not cause allergic reactions.

Isolated cases of side effects have been recorded: a small rash on the skin, headaches and slight dizziness. According to medical statistics, such complications are observed only in 0.1% of cases and are associated with individual intolerance to the drug. Side effects are extremely rare and disappear quickly.

There are several types of contrast agents used in contrast-enhanced MRI. They differ in composition and method of application. Most often, patients are prescribed contrast, which is administered intravenously. This substance contains iron oxide, which helps to obtain the most accurate picture of blood vessels. This contrast is prescribed, for example, for diagnosing multiple sclerosis.

For detailed diagnosis of the patient's gastrointestinal tract, oral contrast agents are used. Such agents may be based on compounds of manganese and gadolinium soda.

They are effective because they contain a high concentration of manganese.

Today, almost 20% of all magnetic resonance imaging scans are performed using a contrast agent. The need for its use is determined by the doctor. Most often, the use of contrast is prescribed for suspected cancer, pathology of the digestive tract, study of the brain, and also for diseases of the spine.

Contraindications

Patients who have repeatedly undergone such examinations and know what MRI is have experienced its effectiveness. Tomography is absolutely harmless, as it does not carry radiation or ionizing radiation. However, even this diagnostic method has contraindications. Since the operation of the tomograph is based on the influence of magnetic fields, people with:

• metal implants;
• neurostimulants;
• clips on vessels;
• heart valves;
• dental prostheses.

Patients with metal implants or intrauterine devices may not be allowed to be examined. The procedure is also strictly not recommended for women who use permanent eyeliner. A contraindication to MRI will be the presence in the patient’s body of fragments from bullets or other types of wounds.

People who suffer from mental illness and claustrophobia may be refused examination. If a person is afraid of closed spaces, examination on an open type device will be recommended. The images obtained with such a tomograph may not be as detailed and accurate as with a closed one, but this will allow the patient to avoid an attack.

Some diseases in the stage of decompensation may interfere with the examination of a person. A refusal may be given to a patient who suffers from:

• bronchial asthma;
• diseases of the cardiovascular system;
• severe dehydration of the body.

Taking certain medications that contain beta blockers is an additional contraindication for MRI.

People under the influence of alcohol or drugs are also not allowed to take part in the study.

A patient with impaired or complete cessation of renal excretory function may also be refused if he has been sent for magnetic resonance imaging using a contrast agent.

Experts also highlight relative contraindications for undergoing MRI, which cause controversy among doctors. It is not recommended to perform tomography on pregnant women under 12 weeks of gestation.

Although studies have not revealed any threat to the intrauterine development of the fetus, the procedure is still not performed. At this stage of pregnancy, the baby undergoes the main processes of formation of internal organs and body systems, so medical workers do not want to take risks.

During this period, the woman is offered to use other modern research methods to make a diagnosis.

Indications for MRI diagnostics

Like any other examination method, magnetic resonance imaging has both strengths and weaknesses, which are quite numerous. When examining some tissues, it provides the most accurate information, while when scanning others, it provides less detailed information. During the use of MRI, experts have compiled a list of pathologies that are recommended for diagnosis using this method.

First of all, the examination helps to detect a large number of brain disorders . Experts identify the following indications for MRI:

• periodic fainting;
• frequent dizziness;
• traumatic brain injuries;
• seizures;
• decreased sensitivity of the facial nerves.

The examination allows doctors to quickly detect metastases and diagnose any inflammatory diseases.

The study is prescribed not only to identify the disease, but also to determine the possibility of its surgical treatment.

Magnetic resonance imaging is very often prescribed to people to study the condition of the spine and spinal cord . The examination helps:

• Determine congenital and acquired anomalies of vertebral development.
• Identify diseases such as: osteochondrosis, intervertebral hernia, radiculitis, arthrosis of the intervertebral joints, disc protrusion , etc.
• Assess the condition of the spinal cord and diagnose its pinching.
• Identify decreased height of intervertebral discs.
• Determine the presence and location of tumor formations.
• Assess the degree of degenerative changes in the spine.

In this regard, the study makes it possible to accurately diagnose the following pathologies: protrusions and herniated intervertebral discs, osteochondrosis, osteoporosis, spinal cord injuries.

gives good results when examining internal organs :

• abdominal cavity and retroperitoneal space: kidneys, liver, pancreas, gall, adrenal glands, spleen;
• pelvis in women and men: ovaries, uterus, scrotum, bladder, prostate, penis, vas deferens, fallopian tubes;
• chest cavity: lungs, thyroid and parathyroid glands;
• nasopharynx: nasal sinuses, maxillary sinuses, pharynx, larynx, soft tissues of the neck.

Preparing for the examination

The undoubted advantage of magnetic resonance imaging is the lack of special preparation for its passage, unlike many other diagnostic methods. The patient does not need to follow a strict diet, refuse to eat before the examination, or otherwise change his usual rhythm of life.

Preparation for an MRI is quite simple, and is mainly associated with the doctor studying the patient’s medical history. Before the study, the specialist must obtain comprehensive information about the patient’s health status, so he:

• conducts a survey;
• clarifies all past pathologies;
• studies the results of previously performed procedures.

This is necessary to prevent errors from occurring during scanning and analysis of the resulting images. The doctor will definitely tell the patient how the study will be carried out and whether preparation for the MRI is necessary.

Women scheduled for examination should remember that it is better not to apply makeup before the procedure, since cosmetic products may contain microparticles of metal.

Such substances can cause distortion of analysis results.

Immediately before the procedure begins, the patient will be asked to remove all metal objects, including earrings, belts, rings, hairpins, and clothes with zippers. The patient will be provided with a special gown that he will have to wear. The patient can also take with him comfortable light clothing in which he will undergo the examination.

If a person is scheduled for an abdominal examination, they may need special preparation before undergoing an MRI. The patient will be advised not to consume food or water 5 hours before the scan.

Patients who need to examine the condition of the pelvic organs are asked to drink a liter of clean water an hour before the examination. This will improve the quality and accuracy of the resulting images.

It is important to remember that such research is not recommended for women during menstruation.

Patients do not need to perform any preparatory steps before starting a spinal column examination. However, you need to know that you will have to remain completely still throughout the scan.

Patients with such problems may be prescribed painkillers before the procedure.

What does an MRI show?

The examination is considered the most effective for identifying brain diseases . After studying the layer-by-layer images of tissues, it is not difficult for a doctor to detect:

• vasculitis;
• increased intracranial pressure;
• stroke;
• aneurysm;
• cerebral infarction;
• neoplasms.

The study allows you to find any inflammatory processes, detect tumors, cysts, hematomas, and ischemic areas.

When studying the test results, the doctor may also identify some ophthalmological diseases.

For example, MRI diagnostics is effective in detecting inflammatory processes in the structure of the eye, metastases that have penetrated the tissues of the organs of vision, thrombosis and injuries to the optic nerve.

Abdominal examination includes examination of the spleen, gallbladder and ducts, pancreas, kidneys and adrenal glands. During the procedure, doctors can detect the following diseases of internal organs :

• pancreatitis;
• cirrhosis of the liver;
• benign and malignant formations;
• cysts;
• liver abscess;
• cholecystitis.

By studying the kidneys and adrenal glands, doctors are able to identify any problems with their functioning, as well as examine the condition of the urinary tract. Even minor anomalies are clearly visible in the images obtained during MRI diagnostics.

A study of the pelvic organs in men reveals prostatitis, vesiculitis, proctitis, prostate hypertrophy, and teratomas. examination may reveal in women :

• endometriosis;
• uterine fibroids;
• adnexitis;
• cysts;
• polyps;
• cancerous tumors.

Magnetic resonance imaging is considered the most accurate method for diagnosing liver tumors. This study is called MR-cholangiopancreatography. It is performed without the use of a contrast agent, helps to study all bile ducts and identify a tumor even at the initial stage of its development.

Of all the methods for studying the condition of the spine, MRI is considered the most accurate and informative. In the photographs, the specialist clearly sees the soft fibers that are located near the spine, all the nerve endings and blood vessels. This gives him the opportunity to study all the processes occurring in this area. MRI diagnostics of the back can reveal:

• displacement of bone structures;
• rheumatoid arthritis;
• narrowing of the spinal canal;
• rachiocampsis;
• Bekhterev's disease.

In addition, MRI helps to identify any vascular abnormalities and circulatory problems. Any infectious tissue lesions are also easily identified when studying the scan results.

How is the research going?

The duration of an MRI scan may vary. Typically, the study takes from 20 to 60 minutes. The duration of the procedure is affected by:

• scope of study;
• number of pathologies and their prevalence;
• the need to use a contrast agent.

Before starting the study, the patient must notify the doctor if he has any contraindications for MRI. For example, if a woman suspects she is pregnant, she needs to tell a specialist about it. Perhaps the doctor will refuse to perform the scan or replace it with a less risky one.

Many patients scheduled for examination are interested in how an MRI is performed. The person is placed on a special couch, his legs, head and arms are secured with special soft belts.

This is necessary in order to prevent any involuntary movements during scanning.

You must lie absolutely still throughout the entire examination. For children, this requirement is often impossible to meet. Therefore, if an MRI is prescribed for a child , then before the procedure he may be given a sedative or given anesthesia in the lungs. When a patient is nervous before a procedure, doctors may advise him to take a sedative.

The table on which the patient lies is slowly moved into the tomograph. The device is a large hollow cylinder. Since the tomograph produces quite sharp and loud sounds during operation, the patient will be asked to use earplugs or headphones with soft music playing.

The results of the MRI study will be ready a few hours after the scan is completed. The images are sent to the attending physician or given to the patient. Since the procedure does not pose any harm to health, it can be repeated many times.

MRI of the spleen: accurate diagnosis of the most mysterious organ

The spleen is part of the reticuloendothelial system, retains iron reserves, dead platelets and other blood cells, participates in the functioning of the immune and hematopoietic system of the fetus, converts hemoglobin into bilirubin, etc. Diseases of this organ usually occur against a background of severe pain and a general deterioration in the person’s condition.

Diagnosis of the spleen is often difficult, since identical symptoms can also appear with pathological changes in neighboring organs. In such cases, the doctor gives a referral for magnetic resonance imaging - the most effective, safe and painless way to diagnose internal organs.

The spleen is one of the little studied and mysterious human organs. Despite the complexity of the structure and the many functions it performs, after removal of the spleen you can live for many more years, and with virtually no restrictions. Still, do not underestimate the importance of this organ.

What does an MRI of the spleen show?

• Splenic infarction. This condition can be caused by twisting of the leg or other malformations of this organ: the so-called. wandering spleen (due to the weakness of connective tissues, it may be located in another place), bifurcated, the presence of an accessory organ. Most of these anomalies require urgent surgical intervention.
• Splenomegaly may go undetected on ultrasound or CT, especially if the enlarged fragment is small or off-center. In such cases, only tomography will help identify a pathological formation that may turn out to be malignant.
• Cysts can be single or multiple. In case of an atypical location or if it is necessary to clarify a previously made diagnosis, magnetic resonance examination can be used. In standard cases, diagnosing a cyst is not difficult.

How is the procedure done?

To obtain the most reliable results, it is necessary to diagnose the spleen using tomographs with a power of at least 1.5 Tesla. A clear image can be achieved by capturing images while holding your breath. The average duration of the procedure is 40 minutes.

Preparation for the examination includes prescribing a carbohydrate-free diet 2-3 days before the procedure. Discontinuation of medications is not required. For better visualization of the image, in some cases an MRI with a contrast agent is prescribed.

It is administered intravenously, after which the drug passes through the tissues and vessels, allowing for a more accurate examination result. You must remain completely still during the scan.
