Overview

Brain tumor MRI

Brain tumor imaging

Magnetic resonance imaging (MRI) is a medical imaging technique that uses a magnetic field and computer-generated radio waves to create detailed images of the organs and tissues in your body.

Most MRI machines are large, tube-shaped magnets. When you lie inside an MRI machine, the magnetic field temporarily realigns water molecules in your body. Radio waves cause these aligned atoms to produce faint signals, which are used to create cross-sectional MRI images — like slices in a loaf of bread.

The MRI machine can also produce 3D images that can be viewed from different angles.

Why it's done

MRI is a noninvasive way for your doctor to examine your organs, tissues and skeletal system. It produces high-resolution images of the inside of the body that help diagnose a variety of problems.

MRI of the brain and spinal cord

MRI is the most frequently used imaging test of the brain and spinal cord. It's often performed to help diagnose:

  • Aneurysms of cerebral vessels
  • Disorders of the eye and inner ear
  • Multiple sclerosis
  • Spinal cord disorders
  • Stroke
  • Tumors
  • Brain injury from trauma

A special type of MRI is the functional MRI of the brain (fMRI). It produces images of blood flow to certain areas of the brain. It can be used to examine the brain's anatomy and determine which parts of the brain are handling critical functions.

This helps identify important language and movement control areas in the brains of people being considered for brain surgery. Functional MRI can also be used to assess damage from a head injury or from disorders such as Alzheimer's disease.

MRI of the heart and blood vessels

MRI that focuses on the heart or blood vessels can assess:

  • Size and function of the heart's chambers
  • Thickness and movement of the walls of the heart
  • Extent of damage caused by heart attacks or heart disease
  • Structural problems in the aorta, such as aneurysms or dissections
  • Inflammation or blockages in the blood vessels

MRI of other internal organs

MRI can check for tumors or other abnormalities of many organs in the body, including the following:

  • Liver and bile ducts
  • Kidneys
  • Spleen
  • Pancreas
  • Uterus
  • Ovaries
  • Prostate

MRI of bones and joints

MRI can help evaluate:

  • Joint abnormalities caused by traumatic or repetitive injuries, such as torn cartilage or ligaments
  • Disk abnormalities in the spine
  • Bone infections
  • Tumors of the bones and soft tissues

MRI of the breasts

MRI can be used with mammography to detect breast cancer, particularly in women who have dense breast tissue or who might be at high risk of the disease.

Risks

Because MRI uses powerful magnets, the presence of metal in your body can be a safety hazard if attracted to the magnet. Even if not attracted to the magnet, metal objects can distort the MRI image. Before having an MRI, you'll likely complete a questionnaire that includes whether you have metal or electronic devices in your body.

Unless the device you have is certified as MRI safe, you might not be able to have an MRI. Devices include:

  • Metallic joint prostheses
  • Artificial heart valves
  • An implantable heart defibrillator
  • Implanted drug infusion pumps
  • Implanted nerve stimulators
  • A pacemaker
  • Metal clips
  • Metal pins, screws, plates, stents or surgical staples
  • Cochlear implants
  • A bullet, shrapnel or any other type of metal fragment
  • Intrauterine device

If you have tattoos or permanent makeup, ask your doctor whether they might affect your MRI. Some of the darker inks contain metal.

Before you schedule an MRI, tell your doctor if you think you're pregnant. The effects of magnetic fields on fetuses aren't well understood. Your doctor might recommend an alternative exam or postponing the MRI. Also tell your doctor if you're breast-feeding, especially if you're to receive contrast material during the procedure.

It's also important to discuss kidney or liver problems with your doctor and the technologist, because problems with these organs might limit the use of injected contrast agents during your scan.

How you prepare

Before an MRI exam, eat normally and continue to take your usual medications, unless otherwise instructed. You will typically be asked to change into a gown and to remove things that might affect the magnetic imaging, such as:

  • Jewelry
  • Hairpins
  • Eyeglasses
  • Watches
  • Wigs
  • Dentures
  • Hearing aids
  • Underwire bras
  • Cosmetics that contain metal particles

What you can expect

During the test

The MRI machine looks like a long narrow tube that has both ends open. You lie down on a movable table that slides into the opening of the tube. A technologist monitors you from another room. You can talk with the person by microphone.

If you have a fear of enclosed spaces (claustrophobia), you might be given a drug to help you feel sleepy and less anxious. Most people get through the exam without difficulty.

The MRI machine creates a strong magnetic field around you, and radio waves are directed at your body. The procedure is painless. You don't feel the magnetic field or radio waves, and there are no moving parts around you.

During the MRI scan, the internal part of the magnet produces repetitive tapping, thumping and other noises. You might be given earplugs or have music playing to help block the noise.

In some cases, a contrast material, typically gadolinium, will be injected through an intravenous (IV) line into a vein in your hand or arm. The contrast material enhances certain details. Gadolinium rarely causes allergic reactions.

An MRI can last anywhere from 15 minutes to more than an hour. You must hold still because movement can blur the resulting images.

During a functional MRI, you might be asked to perform a number of small tasks — such as tapping your thumb against your fingers, rubbing a block of sandpaper or answering simple questions. This helps pinpoint the portions of your brain that control these actions.

After the test

If you haven't been sedated, you can resume your usual activities immediately after the scan.

Results

A doctor specially trained to interpret MRIs (radiologist) will analyze the images from your scan and report the findings to your doctor. Your doctor will discuss important findings and next steps with you.

Video: MRI

An MRI is a very useful tool for helping your doctors see images of the inside of your body, including tissue that can't be seen on a conventional x-ray.

Before your exam, it's very important to fill out the safety screening form carefully. MRI is safe and painless. But metal in the scanner can cause serious safety problems or reduce the quality of the images.

Your health care team needs to know about any metal in your body, even a small shard of metal from an accident. Fillings, bridges, and other dental work typically do not pose a problem. But other metal that has been put into your body might prevent you from having an MRI. That includes some pacemakers, clips for treating aneurysms, and other devices with metal in them.

A nurse may review your health history before your exam. You may be given medications or contrast dye or have blood drawn. Be sure to tell the nurse if you're pregnant, have an allergy to contrast dye, or have kidney or liver problems. You may not wear clothing with snaps or zippers in the scanner. You will be asked to wear a gown. Do not wear any jewelry or bring anything metal into the scanner, including a hearing aid.

An MRI machine uses a powerful magnet to make images of your body. Unlike a CT scan, it does not use x-rays or other radiation. You will be given earplugs. The scanner makes a loud noise when it's operating.

A device called a coil may be put on or around the area to be scanned to help capture the images. You will also be given a squeeze ball to hold. You can use this to signal the technologist any time you need something. The MRI is controlled from a nearby room. You will be closely observed throughout the procedure.

A series of scans are taken with a brief pause between each. You may hear different noises as different scans are taken. It's normal for the noise to be very loud. You need to remain still when the scan is being taken.

People are typically in the scanner from 30 to 50 minutes, depending on the images to be taken. A complex examination can take longer. If you are concerned about being in the scanner for this length of time, talk to your physician and the technologist. They can help you with some tips for staying comfortable.

If you need to be removed from the scanner, this can be done very quickly. The ends of the scanner are always open.

After your exam, the images will be reviewed by your radiologist. He or she will send a report to the health care provider who ordered the test. Ask your health care provider any questions you have about your MRI.

Seeing inside the heart with MRI

Watch how a cardiac MRI uses still or moving pictures to show blood flow through the heart.

Vivien Williams: One out of four, that's how many people will die of a heart related problem. Doctors at Mayo Clinic are trying to improve those statistics. They're using MRIs to look inside the heart to find disease and tailor treatment to keep people healthier longer.

MRI technician: You can breathe. Breathe normal.

Vivien Williams: Magnetic Resonance Imaging, or MRI, allows doctors to look inside the heart as it beats.

Brian Shapiro, M.D., Mayo Clinic cardiologist: You can see here, this is the left ventricle, which is the main pumping chamber that pushes blood out of the body.

Vivien Williams: Dr. Brian Shapiro uses MRI to look for abnormalities in the heart.

Brian Shapiro, M.D.: What the MRI does is it looks at the tissue characteristics of the heart. So, swelling of the heart is a very common thing in heart attacks, and infections, and things like that.

Vivien Williams: The moving or still images show exactly where damage happens.

Brian Shapiro, M.D.: You would see it as a very bright, bright spot in the heart.

Vivien Williams: In addition to damage from heart attack or infection, MRI can also show Dr. Shapiro how well the heart pumps, where irregular heart beats originate, the location of blood clots, artery blockages, scar tissue, or even tumors. Because MRI allows doctors to see more detail of the heart, they can make more accurate diagnoses, and therefore tailor treatment for patients.

Brian Shapiro, M.D.: As you can actually show where the heart attack is, and the extent of the heart attack.

Vivien Williams: Images that tell Dr. Shapiro if a patient will recover, if there's permanent damage, and what treatments might be best. Information from inside the heart that can help Dr. Shapiro and his colleagues better help their patients. Dr. Shapiro says while MRI can show lots of information about the heart, it does not replace other tests such as stress tests or echo cardiograms. It's another option for looking inside the heart. For Medical Edge, I'm Vivien Williams.

What is MRI?

Magnetic Resonance Imaging (MRI) is a non-invasive imaging technology that produces three dimensional detailed anatomical images. It is often used for disease detection, diagnosis, and treatment monitoring. It is based on sophisticated technology that excites and detects the change in the direction of the rotational axis of protons found in the water that makes up living tissues.

 

How does MRI work?

MRI of a knee

MRIs employ powerful magnets which produce a strong magnetic field that forces protons in the body to align with that field. When a radiofrequency current is then pulsed through the patient, the protons are stimulated, and spin out of equilibrium, straining against the pull of the magnetic field. When the radiofrequency field is turned off, the MRI sensors are able to detect the energy released as the protons realign with the magnetic field. The time it takes for the protons to realign with the magnetic field, as well as the amount of energy released, changes depending on the environment and the chemical nature of the molecules. Physicians are able to tell the difference between various types of tissues based on these magnetic properties.

To obtain an MRI image, a patient is placed inside a large magnet and must remain very still during the imaging process in order not to blur the image. Contrast agents (often containing the element Gadolinium) may be given to a patient intravenously before or during the MRI to increase the speed at which protons realign with the magnetic field. The faster the protons realign, the brighter the image.

What is MRI used for?

MRI scanners are particularly well suited to image the non-bony parts or soft tissues of the body. They differ from computed tomography (CT), in that they do not use the damaging ionizing radiation of x-rays. The brain, spinal cord and nerves, as well as muscles, ligaments, and tendons are seen much more clearly with MRI than with regular x-rays and CT; for this reason MRI is often used to image knee and shoulder injuries.

In the brain, MRI can differentiate between white matter and grey matter and can also be used to diagnose aneurysms and tumors. Because MRI does not use x-rays or other radiation, it is the imaging modality of choice when frequent imaging is required for diagnosis or therapy, especially in the brain. However, MRI is more expensive than x-ray imaging or CT scanning.

One kind of specialized MRI is functional Magnetic Resonance Imaging (fMRI.) This is used to observe brain structures and determine which areas of the brain “activate” (consume more oxygen) during various cognitive tasks. It is used to advance the understanding of brain organization and offers a potential new standard for assessing neurological status and neurosurgical risk.

Are there risks?

Although MRI does not emit the ionizing radiation that is found in x-ray and CT imaging, it does employ a strong magnetic field. The magnetic field extends beyond the machine and exerts very powerful forces on objects of iron, some steels, and other magnetizable objects; it is strong enough to fling a wheelchair across the room. Patients should notify their physicians of any form of medical or implant prior to an MR scan.

When having an MRI scan, the following should be taken into consideration:

  • People with implants, particularly those containing iron, — pacemakers, vagus nerve stimulators, implantable cardioverter- defibrillators, loop recorders, insulin pumps, cochlear implants, deep brain stimulators, and capsules from capsule endoscopy should not enter an MRI machine.
  • Noise—loud noise commonly referred to as clicking and beeping, as well as sound intensity up to 120 decibels in certain MR scanners, may require special ear protection.
  • Nerve Stimulation—a twitching sensation sometimes results from the rapidly switched fields in the MRI.
  • Contrast agents—patients with severe renal failure who require dialysis may risk a rare but serious illness called nephrogenic systemic fibrosis that may be linked to the use of certain gadolinium-containing agents, such as gadodiamide and others. Although a causal link has not been established, current guidelines in the United States recommend that dialysis patients should only receive gadolinium agents when essential, and that dialysis should be performed as soon as possible after the scan to remove the agent from the body promptly.
  • Pregnancy—while no effects have been demonstrated on the fetus, it is recommended that MRI scans be avoided as a precaution especially in the first trimester of pregnancy when the fetus’ organs are being formed and contrast agents, if used, could enter the fetal bloodstream.
New open MRI machine
  • Claustrophobia—people with even mild claustrophobia may find it difficult to tolerate long scan times inside the machine. Familiarization with the machine and process, as well as visualization techniques, sedation, and anesthesia provide patients with mechanisms to overcome their discomfort. Additional coping mechanisms include listening to music or watching a video or movie, closing or covering the eyes, and holding a panic button. The open MRI is a machine that is open on the sides rather than a tube closed at one end, so it does not fully surround the patient. It was developed to accommodate the needs of patients who are uncomfortable with the narrow tunnel and noises of the traditional MRI and for patients whose size or weight make the traditional MRI impractical. Newer open MRI technology provides high quality images for many but not all types of examinations.

What are examples of NIBIB-funded projects in MRI?

Replacing Biopsies with Sound
Chronic liver disease and cirrhosis affect more than 5.5 million people in the United States. NIBIB-funded researchers have developed a method to turn sound waves into images of the liver, which provides a new non-invasive, pain-free approach to find tumors or tissue damaged by liver disease. The Magnetic Resonance Elastography (MRE) device is placed over the liver of the patient before he enters the MRI machine. It then pulses sound waves through the liver, which the MRI is able to detect and use to determine the density and health of the liver tissue. This technique is safer and more comfortable for the patient as well as being less expensive than a traditional biopsy. Since MRE is able to recognize very slight differences in tissue density, there is the potential that it could also be used to detect cancer.

New MRI just for Kids
MRI is potentially one of the best imaging modalities for children since unlike CT, it does not have any ionizing radiation that could potentially be harmful. However, one of the most difficult challenges that MRI technicians face is obtaining a clear image, especially when the patient is a child or has some kind of ailment that prevents them from staying still for extended periods of time. As a result, many young children require anesthesia, which increases the health risk for the patient. NIBIB is funding research that is attempting to develop a robust pediatric body MRI. By creating a pediatric coil made specifically for smaller bodies, the image can be rendered more clearly and quickly and will demand less MR operator skill. This will make MRIs cheaper, safer, and more available to children. The faster imaging and motion compensation could also potentially benefit adult patients as well.

Another NIBIB-funded researcher is trying to solve this problem from a different angle. He is developing a motion correction system that could greatly improve image quality for MR exams. Researchers are developing an optical tracking system that would be able to match and adapt the MRI pulses to changes in the patient’s pose in real time. This improvement could reduce cost (since less repeat MR exams will have to take place due to poor quality) as well as make MRI a viable option for many patients who are unable to remain still for the exam and reduce the amount of anesthesia used for MR exams.

Determining the aggressiveness of a tumor
Traditional MRI, unlike PET or SPECT, cannot measure metabolic rates. However, researchers funded by NIBIB have discovered a way to inject specialized compounds (hyperpolarized carbon 13) into prostate cancer patients to measure the metabolic rate of a tumor. This information can provide a fast and accurate picture of the tumor’s aggressiveness. Monitoring disease progression can improve risk prediction, which is critical for prostate cancer patients who often adopt a wait and watch approach.

What is MRI? How is an MRI done?

Magnetic resonance imaging is a modern type of medical research that allows you to get an image of various parts of the body: soft tissues, joints, cartilage, intervertebral discs. Thanks to MRI diagnostics, we get a three-dimensional visual model of various organs and tissues, including the ability to monitor the functioning of the heart, observe the activity of various parts of the brain, and monitor the circulation of fluids in the circulatory system and spinal cord.

Tomograms obtained in the course of magnetic resonance diagnostics contain a lot of information about the organization of tissues and organs in various anatomical zones. During the study, the doctor receives information about the structure of organs, their size, configuration, and a number of other parameters.

MRI can detect a significant number of diseases , including in the early stages of their development. Various inflammatory processes, diseases of the spine, diseases of the joints, tumors, disorders in the nervous and circulatory systems - information about all these deviations can be obtained thanks to MRI.

In the image obtained during magnetic resonance imaging, pathologically altered areas of tissues and organs outwardly differ from healthy ones. This is due to the fact that healthy cells have one signal level, while organs and tissues affected by a disease process give a different signal, changed to one degree or another.

For a number of diagnostic studies , it is preferable to use high-field MRI devices with a voltage of 1.5 T , which allow you to obtain tissue sections with a size of 1-2 mm. Using special software, the sections obtained during the study are converted into a three-dimensional image. Due to the high shooting speed, a moving image can be obtained, similar to high-definition video.

Principle of operation of MRI

The saturation of the cells of our body with hydrogen and the peculiarities of its magnetic properties make it possible to use the tomographic method of research using the effect of resonant absorption of electromagnetic waves by hydrogen protons.

Magnetic resonance imaging scanner takes pictures of sections of the human body, hundreds of millimeters thick , which allows you to assess the state of the body in great detail from cell to cell. The resolution of the tomograph directly depends on the power of the magnetic field , which is measured in Tesla. The image, accordingly, is obtained in more detail, the information content of diagnostics increases.

Many years of experience in the use of MRI diagnostics in the clinical practice of doctors of various specialties allows us to speak about the advantages of magnetic resonance imaging over other introscopic research methods. The diagnostic efficiency of magnetic resonance imaging is higher than, for example, X-ray computed tomography. This is evidenced by better and more informative images obtained by MRI:

  • Three-dimensional image allows you to explore sections in any plane
  • Detailed visualization of joints, muscles, cartilage, soft tissues, ligaments, brain and spinal cord and other areas significantly increases the information content of the study
  • High resolution provides expert image quality with minimal distortion of the information received scanner, are completely harmless to the patient due to the absence of ionizing radiation and radiation exposure. The magnetic field that affects the human body during an MRI does not have any harmful effect on it. The absence of such radiation is a great advantage, and allows you to conduct multiple studies in a short period of time, without causing harm to the body.

    The diagnostic potential of an MRI examination can be enhanced by the use of contrast. At the same time, another advantage of magnetic resonance imaging over other methods is the absence of negative effects when contrast agents are injected.

    Due to the strong magnetic field of the tomograph, there are some contraindications for MRI diagnostics, which are usually divided into absolute and relative.

    Absolute for all MRI techniques is ban on presence in the body of metal foreign bodies , including non-medical ones, for example, metal suture materials, staples, clips, etc.; artificial joints, valves; bullets, fragments; pacemakers, pacemakers, implants in the ears, in vessels, the presence of an artificial eye, piercing, spiral embolus, dental massive prostheses, bridges, etc.

    the physical condition of the patient, the presence of tattoos made with paints containing metal compounds.

    should be wary of MRI in early pregnancy (first trimester). MRI using a contrast agent is contraindicated in pregnancy at any time. During menstruation, MRI of the pelvic organs is not performed. A suitable time for research is 7-12 days of the cycle.

    Special preparation for magnetic resonance imaging is not required. However, there are a number of features that should be remembered when diagnosing the pelvic organs, abdominal cavity and retroperitoneal space.

    The day before such studies, it is recommended not to consume foods that cause increased gas formation, as well as carbonated drinks and sour-milk products. Since it is undesirable to undergo an MRI procedure with a full stomach, it is better to limit yourself to a light breakfast on the day of the examination. It is important to remember that the study is carried out on an empty stomach, so the last meal is allowed at least 5-6 hours before the start of the diagnosis.

    In case of delayed, difficult or systematically insufficient defecation, it is necessary to prepare and empty the bowels in advance. Pelvic examination requires a moderately full bladder.

    A feature of the study of the pelvic organs in women is that the diagnosis is not carried out during menstruation. The optimal diagnostic period is 7-12 days of the cycle.

    The MRI examination process consists of the following sequential steps.

    Prior to the start of the examination, the patient must exclude the presence of all metal-containing items and accessories: watches, jewelry, a lighter, a mobile phone, etc. All these things can negatively affect the magnetic field of the tomograph, distorting the diagnostic data.

    When the patient is ready for the examination, they are placed in the tunnel-like working element of the scanner. A high-field closed-type tomograph with a closed liquid helium cooling system is installed in our center. During the scan, the patient is inside the apparatus, the diameter of which is 60 cm. The tomograph has good lighting and ventilation, which ensure a comfortable procedure.

    The duration of the procedure, depending on the area of ​​study, is from 15 to 40 minutes. It is necessary that the patient did not move while the device was in operation, as this may degrade the quality of the images. In this regard, in special cases, preliminary anesthesia can be carried out.

    During the examination, access to the room with a tomograph is closed, the specialist monitors the readings of the device from a specially isolated room. The patient is under constant supervision of the staff, in his hands is a signal pear (panic button), which he can press if he feels unwell. In this case, the work of the tomograph stops.

    The operation of the device is accompanied by rather loud sounds, provoked by electromagnetic vibrations inside the tomograph. To reduce the noise level, the diagnosed person is given special headphones.

    Application of contrast

    In case of ambiguity in the results of tomography, the specialist may recommend diagnostics with the introduction of contrast, increasing the accuracy of the study . Due to its chemical composition, the injected contrast agent accumulates only in damaged tissues, which allows better visualization of pathological abnormalities, including benign tumors and some types of cancer.

    In addition, it is possible to trace the “path” of the contrast through the blood vessels and evaluate the work of the circulatory system in the study area. The use of contrast improves the visualization of inflammation, tumors, or growth of blood vessels, improves the accuracy of diagnosis in infectious diseases of the brain, spine, soft tissues and bones.

    MRI contrast agents contain gadolinium and are qualitatively different from those drugs that are used in other research methods, since they are based on no substances containing iodine. The human body is much less likely to react negatively to gadolinium than to iodine-containing contrasts. The contrast is administered intravenously to the patient. The duration of the contrast injection procedure takes on average about a minute and does not cause pain .

    It is important to note that the contrast with gadolinium has some contraindications . Thus, the introduction of a contrast agent is not recommended in the presence of impaired renal or hepatic functions. Pregnancy is also a contraindication for the use of contrast. At the same time, the use of contrast during lactation is not contraindicated, since a small amount of gadolinium enters the body, in addition, it is quickly excreted from the body. Nevertheless, experts do not recommend breastfeeding a child for a day after applying a contrast agent.

    What is MRI diagnostics? - Medical clinic "DonMed" in Rostov-on-Don


    MRI or Magnetic Resonance Imaging is a safe and effective diagnostic method based on a magnetic field and electromagnetic pulses. During the study, the patient is placed in the tomograph tunnel. The wide opening for the patient has a socket of 120 cm. The tunnel is open on both sides. Ventilation and lighting are organized for maximum patient comfort during the examination.

    MRI is one of the most effective modern diagnostic tools that allows you to visualize the brain, spinal cord and other internal organs in excellent quality!
    Modern MRI techniques make it possible to study the function of organs - to measure the speed of blood flow, the flow of cerebrospinal fluid, to determine the level of diffusion in tissues, to see the activation of the cerebral cortex during the functioning of the organs for which this area of ​​the cortex is responsible.

    What does an MRI show?

    MRI can be used to diagnose a number of diseases, such as:
    inflammatory processes in organs;
    anomalies in the development of internal organs;
    lesions of the brain and spinal cord;
    malignant neoplasms;
    benign formations;
    aneurysms and stenoses of vessels;
    deformities, inflammatory processes and infectious lesions of the joints and bone tissues.

    MRI is prescribed for:
    examination of intracranial nerves, structures of the brain and spinal cord;
    study of the membranes of the spinal cord and brain;
    surveys of patients with multiple sclerosis and other neurological diseases, as well as stroke survivors;
    ligament and muscle studies; studying the state of articular surfaces;
    soft tissue, joint and vascular examinations: examinations for suspected soft tissue tumors.

    There are some nuances, depending on the specifics of complaints and anamnesis, another type of diagnosis may be needed. To do this, it is advisable to consult with your doctor before undergoing the study.

    After your MRI, you will be given a written report and a CD.

    It is important to understand that the information written in the conclusion is more intended for the doctor who will advise you at the appointment.

    And when you come in for a consultation, don't forget the report and the CD, as most doctors will want to see for themselves the changes that are described in the report.

    Also, if you decide to do the same examination again, it is better to take the previous conclusion with a CD, so that the radiologist can compare the dynamics of your changes and describe it in a new conclusion.

    In the diagnostic center DonMed, the examination is carried out on an expert-class device Philips Achieva 1.5 Tesla — this allows you to perform what previously seemed impossible — a complete diagnosis of the brain and spinal cord in less than 20 minutes!

    How often can I have tests?

    MRI is a modern and safe diagnostic method, therefore, it does not matter how often you undergo this examination.

    MRI is not limited to repeat procedures.
