Magnetic resonance
imaging (MRI)
Magnetic resonance imaging is one of the most effective diagnostic methods. MRI has a number of important advantages. The main one is the absence of X-ray radiation and, consequently, the absence of harmful effects on the human body.
Every day, K+31 doctors detect a large number of diseases using MRI diagnostics. These are various inflammatory processes and tumors, disorders in the functioning of the nervous and circulatory systems, diseases of the spine and joints.
Thanks to the latest high and ultra-high power tomographs, as well as leading radiologists, the Department of Magnetic Resonance Imaging is one of the leading medical areas of K+31.

K+31 clinics are equipped with premium MRI systems that use intelligent scanning technology to perform patient-friendly exams with excellent image quality in the shortest amount of time.
MRI 3 Tesla is almost the maximum value available today in diagnostic practice.
High-field and ultra-high-field MR tomographs in all K+31 clinics:
- - SIGNATM Architect AIRTM Edition 3 Tesla in K+31 on Lobachevskogo.
- - Siemens Magnetom Essenza 1.5 Tesla in K+31 Petrovskie Vorota.
- - GE Signa Voyager 1.5 Tesla in K+31 West.
For your convenience, we work around the clock, so MRI examinations can be done even at night in K+31 on Lobachevskogo clinics.
Appoint to MRI
The SIGNA™ Architect AIR™ Edition is a premium magnetic resonance imaging system with intelligent scanning technology that enables patient-friendly examinations with excellent image quality in a minimum amount of time.
MRI 3 Tesla is almost the maximum value available today in diagnostic practice. Scans with Architect coils provide 360-degree coverage - any type of scan for patients of all sizes.
The versatility of a modern system
This type of MRI allows you to provide stable image quality while reducing the examination time. Thanks to the wide tunnel (700 mm) and the field of view equal to 500x500x500 mm, it is possible to carry out studies of patients with a large physique. In addition, visualization of anatomical structures located far from the center (shoulder, forearm, thigh) can be performed.
The most popular types of magnetic resonance imaging are examinations of the following organs/departments:
- spine;
- brain and head;
- cerebral vessels;
- pituitary gland;
- contrast media studies;
- knee joint and knee;
- elbow joint;
- shoulder joint;
- wrist and hand;
- hip joint;
- ankle;
- abdominal and retroperitoneal space;
- paranasal sinuses;
- sacroiliac joints;
- sacrococcygeal region;
- pelvic organs.
With metal-ceramic dentures, crowns. They are not considered implants. Also, the results are not affected by the intrauterine device. Any metal or ferromagnetic implants are questioned. This also applies to cochlear inner ear prostheses. In these cases, it is necessary to provide the doctor with the implant passport.
Among the contraindications for undergoing MRI are the first 3 months of pregnancy, when fetal organs are laid. During this period, the procedure can be carried out only in case of urgent need and only in the direction of a doctor. The machine is not exposed to X-rays like computed tomography or X-rays. The magnetic field with which the MRI works does not in any way affect the development of the fetus, and for 30 years of using the technology, no negative cases have been identified. Otherwise, MRI is the safest procedure and is used to diagnose the health of both the mother herself and the fetus. The device is able to identify a variety of malformations, diseases and collect all information about the development of the fetus.
Electromagnetic waves and a magnetic field generated during the study do not affect the body of a nursing mother in any way and do not cause any changes in the composition of milk. After the procedure, you can start feeding immediately.
An assistant helps the patient to position himself on the table of the device. One of the conditions is fixation of the examined area of the body to ensure immobility. For this, soft belts and rollers are used. At the same time, the patient does not experience discomfort, he can blink, swallow and talk with the doctor. The investigated part of the body is located in the coil of the apparatus, which emits and receives reflected magnetic waves.
Examination of one organ or part of the body takes 30-40 minutes, but if it is a difficult case, it will take more time. The process itself consists of several series of images, which last for several minutes each. During the operation of the apparatus, it is impossible to move, in the intervals a small movement is allowed, but the examined part of the body must remain motionless. Otherwise, the next series of shots will not coincide with the previous one. For a series of images, the doctor will ask you to hold your breath for 10-15 seconds.
In some cases, solely on the direction of a doctor, the procedure involves the use of a contrast agent. It is previously inserted into a vein in the patient's arm through a catheter. This is an absolutely safe solution, which for some time makes the vessels of the organ under study (for example, the brain) visible to the MRI machine. It does not cause allergic or adverse reactions. Within a day, the substance is naturally excreted from the body without a trace.
The procedure is completely painless. The only thing that can cause a feeling of discomfort is the need to be alone in the office during the study. But the doctor will be in the control room and talk to the patient over the speakerphone. Patients with a fear of a confined space also have nothing to fear. Our apparatus leaves enough open space. In addition, the Siemens tomograph is distinguished by an extremely low noise level during operation. If the study is carried out with a contrast agent, then when it is introduced, the patient may feel cool, a slight rush of blood associated with the entry of the substance into the vessels. The sensations last no more than a couple of minutes.
No, no special preparation is required. But the doctor should be aware of any illnesses you have suffered, recent injuries, surgeries, etc. If you are wearing metal jewelry, you will have to remove them. If the doctor has not limited the intake of medications, food before the MRI, there will be no changes in the usual daily routine.

You can do an MRI with contrast (in the diagnosis of tumors and small anatomical structures) and without contrast, in a state of sleep or without anesthesia:
- Thyroid gland.
- Liver.
- Gallbladder and ducts.
- Pancreas.
- Kidney.
- Spleen.
- Joints.
- Spinal cord.
- Vessels of the head, neck, abdominal region.
- Pelvic organs.
- Soft tissues.
- Lumbar.
- Etc.
Appointment at the medical center for an MRI or a doctor by phone: +7 (499) 999-31-31.
MRI is most often prescribed to diagnose diseases of the brain, intervertebral discs, suspected neoplasms (tumors), determine the pathology of internal organs, to assess surgical intervention and the consequences of injuries.
On average, an MRI examination lasts from 15 to 45 minutes, with the use of contrast, the time increases by 15 minutes.
Duration of MRI diagnostics:
- Knee joints - 20 minutes.
- Brain and neck vessels - 15 minutes.
- Mammary glands - 30 minutes.
- Abdominal organs - 40-45 minutes.
- Organs of the pelvic cavity - 40 minutes.
During the study, you must remain completely still. This should be taken into account in patients with severe pain syndrome. If, due to severe pain, it is not possible to be in a forced position for a long time, then before the examination, it is necessary to perform anesthesia with your doctor or come to the examination after relief of acute pain. If necessary, MRI is performed under sedation with the involvement of an anesthesiologist.
A written conclusion and a computer disk with the obtained images are issued to the patient on the day of the examination. After the examination, based on the results of the scan, you will need to consult a neurologist, traumatologist, surgeon, urologist, gynecologist, or others. The final diagnosis is made by your attending physician and, according to him, prescribes the appropriate treatment.
There are absolute and relative contraindications for MRI. If the patient has absolute contraindications, it is impossible to perform the study; if there are relative contraindications, the issue of conducting the study is decided individually with the MRI doctor performing the study.
Absolute contraindications for MRI:
- The presence of a pacemaker.
- Clips of cerebral vessels after surgical treatment.
- Large metal implants and fragments in the body.
- The presence of metal shavings, fragments in the eye area.
- Middle ear implants (fixed hearing aids).

- Neurostimulators.
- Claustrophobia (fear of closed spaces).
- Decompensated heart failure.
- Hemostatic clips (except for brain vessels).
