What is an MRI of the orbits of the brain. MRI of the eye, optic nerve and ocular orbit - indications and limitations of the diagnostic method. The cost of MRI orbits in the specialized center "Simed"

A modern diagnostic method, MRI of the eye, helps to identify complex pathologies of the eye organs. During a visual examination, the doctor can only examine the outer part of the eye analyzer, its internal sections are hidden under the bones of the orbit. Therefore, for the diagnosis of pathologies that affect the eyes, one cannot do without magnetic resonance imaging.

An analysis of new medical examination methods showed that MRI is gaining popularity, this is due to the information content of the technique. And last but not least, with its safety, even for children. How it works? The local action of the magnetic field causes resonance in the tissues. Experts have determined the permissible parameters of the resonance impulse for each tissue structure. When deviations are visualized, pathology is suspected. MRI is used to detect eye diseases and visual impairment. The advantage of this method is that it can be used at any age, the tomograph boasts the least number of contraindications, with a high accuracy of the result.

The method is absolutely painless. The patient is placed in the tomograph tunnel, where it is necessary to stay motionless for 30 to 40 minutes. Discomfort is observed only.

When is an MRI of the orbits and optic nerve performed?

This method is indispensable in ophthalmology, as it helps to clarify the nature of pathological changes in the region of the eye orbits. There are a number of indications for magnetic resonance imaging:

• if there is a suspicion of blockage of the arteries of the eye by a thrombus;
• the shell of the eye has inflammatory lesions;
• the presence of hemophthalmos, hemorrhage in the eye;
• neoplasms of various etiologies;
• there is a need to monitor the condition of the eyes after injury;
• the presence of congenital pathologies of the eye analyzer;
• pathology of the veins or arteries of the eye is one of the indications for an MRI of the brain and orbits;
• pain in the eye area, which has a recurrent course;
• when monitoring the state of the eye analyzer after surgery;
• in the event of a rapid deterioration in the quality of vision.

MRI helps to identify pathologies of any etiology, even if they are infectious and inflammatory processes, autoimmune or congenital defects in the structure of the eyes.

MRI of the eyes is forbidden to do in the presence of a pin in the tooth or metal crowns

What does an eye MRI show?

Based on the indications, it is easy to determine which changes can be visualized when performing magnetic resonance imaging. Given that the optic nerve is anatomically made up of millions of sensory fibers, special attention is paid to its examination. A three-dimensional image of the eye is displayed on the screen to show its systemic structure. The integrity of structures is assessed - nerves, blood vessels, fatty tissue.

You can see damage to the eye muscles that perform the motor function of the eyeball. The pictures will visualize blood flow disorders, this often happens with injuries, tumor-like neoplasms will be visible.

MRI of the orbit of the eye makes it possible to examine the part of the tissues between the wall of the orbit and the eye itself - the retrobulbar space.

How to prepare for the examination?

First of all, the patient is explained the purpose of the examination. It is important to know that throughout the procedure it is necessary to remain still. This is necessary in order for the image to be as clear and informative as possible.

If an MRI of the eye orbits and optic nerves is performed, the doctor makes a test for the individual tolerance of the reagent. In this case, you should not eat a few hours before the procedure.

For the period of diagnosis, you need to get rid of the lenses if a person wears them constantly or periodically. The duration of the procedure is no more than an hour, in the case of the introduction of a contrast agent, tomography can be delayed for 1-1.5 hours, it all depends on which area is being examined.

What are the contraindications?

As with any other diagnostic method, a number of contraindications can be distinguished during a computer examination in a tomograph:

1. If there are implanted metal elements in the human body - pacemakers, pins, knee prostheses. In the case of an IVR, magnetic fluxes can disable it.
2. The serious condition of the patient is regarded as an obstacle to the examination. How to explain it? The presence of an endotracheal tube and cardiac monitor sensors is unacceptable in the tomograph tunnel.
3. Allergy to the injection of a contrast agent.

Is the procedure safe for the organs of vision?

MRI of the optic nerve and the eye as a whole is the safest method for diagnosing ophthalmic pathologies:

• there is no radiation exposure, this allows you to carry out the procedure several times in a row;
• there is no need to penetrate the structures of the eye with additional tools;
• high information content, unlike CT, MRI provides better visualization of soft tissues, blood vessels, nerves;
• can be carried out even for children, subject to immobility.

By prescribing resonance imaging, the doctor assesses the condition of the person, the internal potential for recovery, the severity of the pathology, and so on. The speed of processing the results of MRI of the eye orbits and optic nerves depends on the workload of the office. As a rule, the results will be ready in 2-3 hours. The patient, turning to a radiologist, receives all scanned images with processing and a conclusion.

Where to go with the results?

Ophthalmologists prefer magnetic resonance imaging, due to its effectiveness and safety. Having received all the necessary data after the examination, you need to go to a qualified doctor who will draw up an individual treatment program.

In almost any medical institution that has an MRI machine, you can undergo an eye examination. In the healthcare system, it is important to trust clinics with the latest equipment and experienced doctors. Very often, the diagnosis of ophthalmic diseases is carried out using angiographer:

Magnetic resonance imaging is a method of diagnostic examination of various human organs, combining the knowledge of nuclear physics and medicine. This method is a little less than 60 years old, but it began to be actively used only at the turn of the last and present centuries directly for the study of internal organs and the brain. A little later, the method gained great popularity in ophthalmology for the diagnosis of eye diseases, the cause of which is not visible during visual examination. MRI of the orbits and optic nerves allows you to detect the slightest changes in various tissues and structures of the eye that affect a person's ability to see. This means that this method helps to identify the disease in its initial stage and begin treatment when it is most effective.

Indications

Magnetic resonance imaging is considered one of the safest and most effective ways to identify various eye pathologies by carefully examining internal structures that are not visible to the naked eye and are not visible during the examination with a microscope. In addition, the more modern MRI method helps to see such tiny changes in the eye that are inaccessible to the study of old methods.

Due to the high diagnostic value of MRI of the orbits, it can be prescribed for the diagnosis of a variety of eye pathologies:

• inflammatory processes with localization in different layers of the organ of vision,
• damage to the retina, for example, its detachment,
• tumor processes in the organ area with the determination of their exact location and size (even neoplasms of small sizes from 1 mm are determined),
• hemorrhages in the eye with the definition of their cause, thrombosis of the vessels of the eye,
• injuries with determination of the severity and volume of damaged tissues, with the identification of remnants of foreign bodies that caused eye injury,
• corneal changes,
• impaired functioning of the optic nerves (for example, if glaucoma is suspected), decreased visual acuity, the appearance of incomprehensible pain in the eye with the determination of their cause,
• the state of the organ of vision in diabetes mellitus, hypertension and other pathologies in which the blood supply to the eye is disturbed.

Using MRI, it is possible to determine the location of foreign bodies in the internal structures of the eye, identify inflammatory foci and evaluate their size, find hidden tumors, and, under MRI control, take material for a biopsy.

If there has been an eye injury, MRI allows assessing its consequences and complications, the size and nature of damage to internal structures as a result of the injury, and the possibility of treatment in each specific case.

When a person's vision deteriorates or the motor activity of the eyes is impaired (strabismus appears, the patient cannot focus on a specific object), it is simply impossible to determine the cause without examining the internal structures. MRI makes it possible to see and assess the degree of damage (atrophy) of the muscles or nerves responsible for eye movement, and outline measures to correct the defect.

Quite often, the cause of visual impairment and pain is hidden from us, and it can be detected only by virtually penetrating inside the eye, observing its work, evaluating the changes taking place there. This is precisely what magnetic resonance imaging provides. And although the procedure is called MRI of the orbits, in fact, it also allows you to visualize disorders of the visual muscles, nerves and lacrimal glands, pathology of the eyeball, changes in fatty tissue, due to which its demand is growing more and more.

Training

MRI of the orbits and optic nerves is considered a simple and generally safe procedure that does not require special measures to prepare for diagnosis. Usually it is prescribed by an ophthalmologist during the reception and examination of the patient, if making an accurate diagnosis causes him difficulty.

A person can undergo an examination on the same day or later, when such an opportunity arises. The fact is that not all medical institutions are equipped with the necessary equipment. In addition, the MRI procedure will not be free for everyone.

The main condition for obtaining a high-quality image is the immobility of the patient during the examination, about which the person is warned in advance. If the patient is very nervous, he has symptoms of claustrophobia or severe pain that does not allow him to remain still, sedatives are indicated that reduce nervous excitability.

Patients with mental disorders or serious eye injuries, in which they experience unbearable pain, require additional fixation of the limbs. If the above measures do not help, the doctor may resort to anesthesia administered intravenously.

Since the study of organs is carried out using a magnetic field, any metal objects that can distort it must be removed. We are talking about jewelry and clothing with metal elements (locks, buckles, buttons, buttons, decorative overlays, etc.). If there is metal in the body in the form of crowns, organ implants, electronic devices that support body functions, you need to tell the doctor about it at the time of admission. It may be necessary to clarify the material of dentures if the patient is not sure of his information.

During MRI, contrast agents can be used, which facilitate the diagnosis of tumor and inflammatory processes, and help assess the condition of blood vessels. This question is also discussed in advance, because on the eve of the procedure (5 hours before it), the patient will have to refuse food so that none of the food components could affect the result of the study. The best option is the introduction of contrast on an empty stomach.

To exclude intolerance to the contrast agent and anaphylactic reactions, a test is carried out before the administration of the drug, applying the drug to open areas of the skin in the wrist area. The doctor must specify the weight of the patient, because the amount of injected contrast depends on this.

The drug is administered intravenously in the form of injections or infusions (drip) into the elbow area. At the same time, the patient may feel dizzy, fever, hot flashes, nausea, but this is not scary, since it is considered a normal reaction of the body to contrasts. The introduction of preparations for MRI of the orbits with contrast is carried out under the supervision of a doctor. Over the next 30 minutes, the patient is monitored by medical staff.

Half an hour after the administration of drugs, the active substance of which accumulates in different tissues in various concentrations, you can proceed to MRI diagnostics. During this time, the medicine will spread through the bloodstream and reach the area under study.

Technique for MRI of the eye orbits

MRI of the orbits, like any other diagnostic procedure, is not carried out for the sake of interest. Therefore, it must be taken seriously. After examining the patient by a specialist, he gives a referral for a diagnostic study. With this direction and the results of previous studies of the organs of vision, the patient is sent to the diagnostic room.

The radiography we are used to is somewhat different from the magnetic resonance imaging, although both studies are identical and pursue the same goals. An uninitiated person may be a little shocked by the apparatus in the form of a long volumetric pipe located horizontally. It is in this tube (capsule) that a magnetic field is created, which makes it possible to obtain an image of the organ under study in all details on the screen.

To relieve tension and fear of the apparatus and procedure, the patient is explained how an MRI of the eye is done, that the procedure can show in each case what consequences this study has for the body.

The principle of operation of magnetic resonance installations of an open or closed type is based on fixing the movement of hydrogen atoms that saturate the tissues of the body under the influence of a magnetic field. The illumination of different parts of the image depends on the number of gas molecules accumulated there.

The MRI procedure is quite difficult to perform and requires the patient to remain still. The easiest way to do this is in a horizontal position, when the person is as relaxed as possible. For these purposes, a retractable table is provided in the tomograph, on which the patient is placed, fixing his head in a special device. If necessary, other parts of the body can also be fixed with belts.

Since only the head area is examined, the table is shifted in such a way that only it is inside the apparatus. The torso is outside the tomograph.

Before starting the procedure, patients are advised to use earplugs, since the apparatus is characterized by a not very pleasant monotonous sound, which can cause anxiety and cause unwanted movements.

The procedure itself, compared with x-rays, is considered quite lengthy. In time, it takes from 20 to 40 minutes, during which the person must lie still. If contrast agents are used during the study, the procedure may take another twenty minutes.

During the examination, the doctor is usually outside the diagnostic room, but the patient can contact him at any time on the speakerphone if there is an attack of claustrophobia or any other problem, such as chest pain, shortness of breath, feeling short of breath, which happens during the procedure with contrast. In the same way, the doctor can give the necessary instructions to the patient.

To reduce nervous tension and calm the subject, it is allowed to invite relatives to the procedure. This is especially important if the diagnosis is carried out on a child. Still, the MRI machine is universal, therefore it is large and can frighten a small patient.

Contraindications for carrying out

Magnetic resonance imaging (MRI) is considered one of the safest procedures because, unlike computed tomography (CT) and X-rays, it does not require the use of harmful x-rays. The magnetic field in the tomograph does not harm the health of a person of any age and condition, therefore, health disorders are rather indications for the study than contraindications to it.

The only absolute contraindication to MRI is the presence of ferromagnetic alloys and electronic devices (pacemakers, electronic middle ear implants, etc.) in the human body. The magnetic field can adversely affect the operation of the pacemaker, imitating the heart rhythm and cause malfunctions in the operation of electronic microscopic equipment implanted in the body.

As for metal implants made of ferromagnetic alloys and metal fragments stuck in the body (for example, after injuries), the danger of a strong magnetic field is that under its influence ferromagnets can noticeably heat up, causing tissue burns, and move. Thus, the magnetic field can adversely affect ferromagnetic and large metal implants, Elizarov devices, ferromagnetic middle ear simulators, inner ear prostheses containing ferromagnetic elements, ferromagnetic vascular clips installed in the brain area.

Some metal implants (insulin pumps, nerve stimulators, valvular prostheses, hemostatic clips, dentures, braces, endoprostheses, etc.) can be made from materials that have weak ferromagnetic properties. Such implants are classified as relative contraindications, but they must be reported to the doctor, indicating the materials from which the device is made. After all, even these devices may contain ferromagnetic elements, and the doctor must assess how dangerous the effect of a magnetic field on them will be.

As for dentures, most of them are made of titanium, a metal with weak ferromagnetic properties, i.e. the magnetic field during MRI is unlikely to cause reactions from the metal. But titanium compounds (for example, titanium dioxide used in tattoo inks) can react differently to a strong magnetic field, causing burns on the body.

In addition to non-ferromagnetic implants, relative contraindications include:

• early pregnancy (there is not enough information about the effect of the magnetic field on the development of the fetus during this period, but this method is considered more preferable and safer than CT or X-ray),
• heart failure in the stage of decompensation, serious condition of the patient, the need for constant monitoring of the body, bronchial asthma, severe dehydration
• fear of closed spaces or claustrophobia (due to the inability to conduct research in a person who, out of fear, cannot remain motionless for half an hour or more),
• inadequate condition of the patient (alcohol or drug intoxication, mental disorders will not allow you to take clear pictures due to constant motor reactions),
• tattoos on the body made using paints containing metal particles (there is a risk of tissue burns if these are ferromagnetic particles).
• inner ear prostheses that do not contain ferromagnets.

In these cases, the decision on the possibility of MRI of the orbits is made by the doctor, taking into account the possible negative impact. In some cases, it is more expedient to postpone the procedure for the time necessary to normalize the patient's condition.

If we are talking about an MRI with contrast, the list of contraindications becomes longer, after all, it requires the introduction of chemicals into the body, the reaction to which can be dangerous.

MRI with contrast is not performed:

• pregnant women, regardless of the gestational age due to the ease of penetration of drugs through the placental barrier (the effect of contrasts on the fetus has not yet been studied),
• in chronic renal failure (contrast is excreted from the body within 1.5-2 days, but in case of impaired renal function it can be delayed for a longer period, because the recommended intake of a large amount of liquid is considered unacceptable),
• with hypersensitivity to contrast agents due to the risk of developing severe allergic and anaphylactic reactions.
• patients with hemolytic anemia.

Before the MRI procedure, for their own benefit, the patient is obliged to tell about any metal objects in his body, including fragments from injuries, tattoos and cosmetics used (or better not to use cosmetics), remove all types of jewelry, watches, clothes with metal elements.

Normal performance

MRI of the orbits and optic nerves is a diagnostic study that is prescribed for a specific purpose. The purpose of the study is to identify pathological processes in the tissues of the eye or evaluate the results of treatment if MRI is prescribed again.

MRI allows you to study in detail the shape and quality of the development of the orbits, the location and shape of the eyeballs, the condition of the fundus, the structure and course of the optic nerve, to identify degenerative changes in it and other deviations.

Using MRI of the orbits, it is possible to assess the condition of the eye veins and muscles responsible for the movements of the eyeball (their location, the presence of seals and tumors), the fatty tissue of the orbits.

An MRI can detect damage to the retina, which is the inner lining of the eye. The fact is that damage to the retina does not have to be associated with trauma to the eye or head. Some pathologies of the inner lining of the organ of vision are associated with various systemic diseases (diabetes mellitus, hypertension, pathologies of the kidneys and adrenal glands). Magnetic resonance imaging helps to identify pathologies such as retinal detachment, diabetic or hypertensive retinopathy, damage to blood vessels that provide nutrition to the retina, dystrophy or degeneration of this part of the eyeball, tumor and inflammatory processes, retinal rupture.

MRI of the orbits with contrast allows you to assess the state of the vessels of the eye, their blood supply, the presence of blood clots and ruptures. With the help of contrast agents, it is easier to recognize internal inflammations. But most often the technique is still used to detect tumors in case of suspected oncology. With the help of MRI, you can not only detect a tumor in a certain area of ​​the eye, but also evaluate its shape and size, the presence of metastases, the impact on nearby structures and the possibility of removal.

Any deviations in the shape, size, density of tissues detected by MRI of the orbits provide the doctor with valuable information necessary for making a final diagnosis. In addition, during diagnostic measures, some damage to the brain can be detected, which is also visible on the tomogram.

An example of an orbital MRI protocol might look like this:

Research type: primary (if the study is repeated, also indicate the date of the previous one, with which the results will be compared).

The eye sockets have the correct development, a pyramidal shape with clear and even contours of the walls. Foci of destruction or seals are not observed.

The eyeballs are spherical and symmetrical in relation to the orbits. The tissues of the vitreous body are homogeneous, no changes in the MR signal are observed (this indicates the normal state of the organ, for example, in inflammatory processes, the MR signal will be hyperintense, in tumors - isointense or hyperintense).

Thickening of the membranes of the eye is not observed. They have smooth and clear contours.

The optic nerves are characterized by the correct course and clear contours without dystrophic changes or local thickenings.

Orbit structures: The muscles of the eyeball have the correct location, there are no thickenings on them. Adipose tissue, eye vessels and lacrimal glands without features. Furrows of the convexital surface of the brain without changes.

Visible brain structures: No displacement of median structures. The cisterns of the cerebral base are not deformed. The lateral ventricles of the brain are of normal size and symmetrical arrangement. Areas of pathological density in the area of ​​brain structures are absent.

Other finds: No.

The protocol (decoding) of MRI described above indicates that no pathological changes in the organs of vision in humans have been identified.

After receiving a picture and a study protocol (and they will have to wait about 30 minutes), the patient is sent to an appointment with an ophthalmologist, and sometimes a neurologist to make a final diagnosis and prescribe the necessary treatment.

MRI of the orbits is a non-invasive procedure, i.e. It is possible to examine the internal structures of the eye without opening the tissues. This is another advantage of the modern diagnostic method.

Under the control of MRI, additional diagnostic studies can be carried out, for example, a biopsy if a malignant tumor process inside the eye is suspected. Yes, and a tumor can be easily detected at an early stage of its development with a small size. This helps to make a perfect MRI with contrast.

A three-dimensional image allows you to assess the state of the organ in all details, the only thing that cannot be obtained is a clear image of the walls of the orbits, but all other structures are determined with great accuracy and without the health hazard that exists during CT. The safety of the magnetic resonance method allows it to be used in the diagnosis of ophthalmic and other diseases in children. True, the procedure is prescribed for children over 7 years old, who are already able to be motionless for a long time and fulfill the doctor's requirements.

The disadvantages of the method are the high cost, the relatively long duration of the procedure with the need to maintain a static position during the entire examination period (which is not as simple as it seems), the likelihood of heart rhythm disturbances and a large number of contraindications associated with metal and electronic implants.

However, safety for the body is more important than any money, and time is not an issue when it comes to accurate diagnosis and human health. Those categories of people who cannot undergo an MRI examination may resort to other diagnostic methods (X-ray, slit lamp, eye biomicroscopy, etc.), so that they will not be left without the help of doctors.

Complications during an MRI of the orbits can only occur if contraindications to the procedure are ignored. And then in most cases they are limited to minor tissue burns or distortion of the results of the study, if the patient does not declare a tattoo or implant. Usually, those people who are fitted with devices that control the functioning of vital organs and systems do not forget about them and always report them before prescribing diagnostic studies. But if the information was hidden intentionally, this is the responsibility of the patient himself, who was informed about the requirements for high-quality diagnostics even before the procedure began.

In the Open Clinic, tomography is performed with and without a contrast agent. MRI of the orbits does not bring pain. Patients with claustrophobia are advised to undergo an examination in open-type equipment. In such a device, patients will feel comfortable. Patients should lie still during the examination. Then high-quality images of the studied area will be obtained.

Diagnostics in our clinic lasts about twenty to thirty minutes. The interpretation of the received images is carried out by experienced specialists. The results of magnetic resonance imaging are provided electronically. If any pathologies are detected during an MRI of the eye orbits and diagnostics of the optic nerves, you can immediately sign up for treatment at our medical center.

To use the services of the "Open Clinic", call the contact number listed on the site. Administrators will answer any of your questions and advise on the cost of the study. We have affordable prices for diagnostics.

Indications

• Visual impairment
  The procedure is performed on patients who have suddenly lost their vision. Diagnosis helps to establish the cause of this condition and prescribe timely treatment.
• foreign body
  An MRI of the orbits is performed if there is suspicion of a foreign object in the eye. Diagnostics allows you to determine the location of the foreign body
• Symptoms of unknown etiology
  Tomography is performed if the patient is worried about severe pain in the eye sockets. The reason for the diagnosis is pain in the eyes
• Pathologies
  The procedure is prescribed to patients for the diagnosis of tumors, thrombosis, aneurysms, atrophy of the optic nerve. Diagnosis helps to create an effective treatment regimen
• Injuries
  The study is carried out if the patient has severely injured the eye. Diagnostics allows you to determine the degree of damage and prescribe appropriate therapy
• Ineffectiveness of other methods
  An examination of the orbits using MRI is performed if other methods have not helped to make a final diagnosis and draw up a treatment regimen for the patient

Preparation for the procedure

Before conducting magnetic resonance imaging, the patient should always consult with the attending physician. The specialist should talk about the features of the procedure and the stages of preparation for the study. If a patient is scheduled for magnetic resonance imaging using a staining agent, then he needs to:

• learn about contraindications;
• come for an MRI on an empty stomach;
• warn the doctor about a possible allergy to the drug.

It should be borne in mind that the procedure using contrast should not be done to women who are expecting a child. The presence of metal-containing elements is a contraindication to the study. Therefore, before the diagnosis of the orbits using MRI, patients with pacemakers, built-in hearing aids, implants should consult with their doctor. If possible, braces and dentures should be removed. The patient, before entering the office where the study is being conducted, must get rid of:

• jewelry;
• metal products;
• electronic appliances.

They can not only interfere with the procedure, but also harm the patient. Experts recommend bringing the results of previous studies to magnetic resonance imaging. They will help diagnosticians evaluate how the state of the eye orbits and optic nerves has changed. If all the recommendations of specialists are followed, the diagnosis will be successful and will help the patient to prescribe effective timely treatment.

Price for MRI of the eye orbits and optic nerves

In our medical center, an acceptable cost of diagnostics. Magnetic resonance imaging is available to almost all residents of the capital and the Moscow region. When using a coloring agent, the cost of the study will increase.

The method of magnetic resonance imaging is used in ophthalmology to clarify the nature of pathological changes in the region of the eye orbits. Accurate diagnostics is carried out using electromagnetic pulses of directional action. In the resulting picture, you can see changes in the structure of the elements of the eye, the presence of tumors, hemorrhages.

The high cost of the survey is fully justified by its effectiveness. MRI of the eye orbits and optic nerves allows you to identify defects that cannot be detected by other methods. This allows you to start treatment on time, partially or completely restore vision. Contrast-enhanced MRI allows to detect tumors at an early stage, as well as to study in detail the condition of the eye vessels.

Indications for MRI of the eye

Such an examination is prescribed in the following cases:

• It is necessary to study the condition of the eyes after a traumatic brain injury;
• There is damage to the soft tissues of the eyes, as well as the orbit;
• There is a suspicion of blockage of blood vessels by blood clots during a stroke;
• An examination of the eye vessels is required due to the presence of congenital pathology of the veins and arteries of the brain;
• A brain tumor is found that causes vision changes;
• Often there are unexplained headaches, as well as pain in the eyes;
• It is planned to remove the tumor of the eye;
• Postoperative monitoring of the condition of the eyes.

An indication for examination is the appearance of inflammatory processes in the eye, lacrimal ducts. The method is effective in retinal detachment, optic nerve atrophy. Eye tomography is used for a detailed examination when foreign particles enter.

Symptoms for which patients may be referred for such an examination are severe headaches, a sharp deterioration in vision, pain in the orbits, lacrimation and discharge of pus from the eyes, a decrease in the viewing angle, redness and swelling of the eye tissues.

What does an MRI of the eye show?

A three-dimensional image of the eye is obtained on a computer screen. It shows:

• Inflammation or damage to the eye sockets;
• Pathology of the eyeball;
• Expansion, narrowing, damage to the ophthalmic arteries and veins;
• Damage to the muscles responsible for the movement of the eyeballs;
• Condition of the optic nerve;
• Changes in fatty tissue around the eye.

MRI of the orbits also allows you to examine the area between the eyeball and the wall of the orbit (retrobulbar space), to detect a foreign body that has got there.

The resulting tumors are clearly distinguished in the picture, as well as any disturbances in the blood flow that occur during injuries. With the help of such an examination, it is possible to establish the cause of increased eye pressure, the appearance of glaucoma.

The study of the inner surface of the eyeball (fundus) allows you to study the structure of the optic nerve and blood vessels, to detect pathologies associated with diseases such as diabetes mellitus, heart failure. With the help of MRI of the orbits and the fundus, retinal detachment and malformations can be detected.

Safety and contraindications

MRI of the eye orbits, unlike computed tomography, is used to monitor the healing process of the eye after surgery. The method can be used to diagnose inflammatory processes, to monitor the dynamics of the process of restoration of eye tissues after injuries. This is due to its safety, since no harmful x-rays are used in a magnetic resonance tomograph.

This method has contraindications. Staying in the electromagnetic field is contraindicated for people who have devices implanted in the body to regulate the heart rate, enhance hearing. The magnetic field damages the devices, which can cause deterioration in the condition of patients. The procedure should not be performed if there are metal particles or medical devices in the body.

MR tomography with contrast is not used for women in the first trimester of pregnancy, while breastfeeding.

Eye MRI preparation and procedure

The patient is warned that any metal objects (jewelry, keys, hairpins) can interfere with obtaining an accurate image and reliable results. It is also forbidden to take mobile phones, electronic cards with you to the MRI procedure of the orbits, as they can distort the results. In addition, the magnetic field will erase information from them.

If contrasting is necessary, an allergy test is performed before the administration of the drug: the contrast agent is injected subcutaneously. If the reaction is negative, then the substance is administered intravenously. It enters with blood into the vessels of the eye.

MRI of the eye orbits is a modern method for diagnosing various diseases of the eyeball, pathological processes in the orbit, damage to the optic nerve, and assessment of adjacent tissues.

MRI of the eye is a very effective and efficient method of examination, as it allows not only to examine the pathological area, but also to simulate various processes in volume in several projections. Also, adjacent tissues are examined: eye muscles, optic nerve, retrobulbar space, blood vessels, fatty tissue.

The MRI of the eye orbits itself takes about 20 minutes, with contrasting, the examination time increases to 40 minutes. This examination does not require special preparation, the patient simply comes to the diagnosis at the appointed time.

The procedure is safe for the patient, the contraindications are the same as the general contraindications for magnetic resonance imaging:

• pacemaker;
• Metal structures in the body;
• If MRI with contrast is required, pregnancy is a contraindication;
• Individual allergic reaction to a contrast agent;
• Psychological discomfort in a confined space.

Early MRI diagnosis of diseases of the eyeball and orbit allows not only to stop the pathological process, but also to restore vision.
