MRI
What is 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, therefore, no harmful effects on the human body. The study is carried out using a magnetic field, which has a minimum range of readings. During diagnostics, the machine emits radio waves, which are not as harmful as X-rays.
Every day, doctors at the K+31 Medical Center in Moscow detect and help identify a large number of pathologies and diseases using MRI diagnostics with and without contrast. 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 specialties at K+31.

Features of the tomograph at the K+31 medical center in Moscow
SIGNA™ Architect AIR™ Edition is a premium MRI system that uses intelligent scanning technology that allows perform patient-friendly examinations with excellent image quality and accuracy in a minimum amount of time.
MRI 3 Tesla is almost the maximum value available in diagnostic practice today. Scanning with Architect coils provides 360-degree coverage – scans of any type for patients of all sizes.
The versatility of the modern system
MRI of this type allows for stable image quality and high accuracy while reducing examination time. Thanks to the wide tunnel (700 mm) and field of view of 500x500x500 mm, examinations of large patients are possible and large weight In addition, visualization of anatomical structures located far from the center (shoulder, forearm, thigh) can be performed.

Answers to popular questions
What implants can be used for MRI?
With ceramic-metal dentures, crowns. They are not considered as implants. Also, MRI results do not depend on the presence of an intrauterine device. Any metal or ferromagnetic implants are questionable. This also applies to cochlear prostheses in the inner ear. In these cases, it is necessary to provide the doctor with an implant passport.
Is it possible to do an MRI during pregnancy and how does MRI affect the fetus?
Among the contraindications for MRI are the first 3 months of pregnancy, when the fetal organs are laid down. During this period, the procedure can be carried out by pregnant women, usually only in case of urgent need and only in the direction of a doctor. The device does not emit X-rays, as with computed tomography or X-rays. The magnetic field with which MRI works does not affect the development of the fetus in any way, and for 30 years of using the technology, negative cases have not been identified. Otherwise, the MRI method is the safest procedure and is used to diagnose the health of both the mother and the fetus. The device is able to detect a variety of malformations, diseases and collect all the information about the development of the fetus.
Does MRI affect the body while breastfeeding?
The electromagnetic waves and the magnetic field generated during the study do not affect the body of the nursing mothers and do not cause any changes in the composition of milk. After the MRI, you can immediately start feeding.
What is an MRI procedure?
The assistant helps the patient to sit on the table of the device. One of the conditions is the fixation of the examined area of the body to ensure immobility. For this, soft belts and rollers are used. The patient does not experience any discomfort he can blink, swallow, and talk to a doctor. The part of the body to be examined is located in the coil of the apparatus, emitting and receiving reflected magnetic waves.
Examination of one organ or part of the body takes 30-40 minutes, however, if it is a complex case, more time will be needed. The process itself is a series of shots that last for a few minutes each. During the operation of the device, you can not 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 match the previous one. To take a series of shots, the doctor will ask you to hold your breath for 10-15 seconds.
How is an MRI with contrast performed?
In some cases, only in the direction of a doctor, the procedure involves the use of a contrast agent. This method is used for suspected oncology, oncological processes and for the early detection of metastases that require immediate treatment. A special substance is first injected into a vein in the patient's arm through a catheter. It 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 and adverse reactions. During the day, the substance is completely excreted from the body in a natural way.
How does an MRI feel?
The procedure is completely painless. The only thing that can cause a feeling of discomfort is the need to be on time. studies alone in the office. But the doctor will be in the control room and talk to the patient on the speakerphone. Patients with a fear of confined spaces also have nothing to fear. Our apparatus leaves enough open space. In addition, the Siemens tomograph is characterized by an extremely low noise level during operation. If an MRI study is performed with a contrast agent, then when it is administered, the patient may feel cool, a slight rush blood, associated with the entry of a substance into the vessels. The sensations last no more than a couple of minutes.
Do I need to prepare for an MRI?
No, no special preparation is required. But the doctor needs to know about your past illnesses, recent injuries, surgeries, etc. If you are wearing metal jewelry or other metal items, you will need to remove them. If the doctor did not limit the intake of drugs, food before the MRI, no changes does not occur in the usual daily routine.

Conducting an MRI study
MRI is most often prescribed (in combination with other data from laboratory and instrumental studies), to clarify or establish a diagnosis, identify vascular anomalies, for early diagnosis of diseases brain, intervertebral discs, with multiple sclerosis, with suspected neoplasms (tumors), determining the pathology of internal organs, to assess surgical intervention and the consequences of injuries.
On average, an MRI examination lasts from 15 minutes to 1 hour, when using contrast, the time increases by 15 minutes.
Duration of MRI diagnostics:
- MRI of the knee joints – 20 minutes.
- MRI of the head, brain and MRI of neck vessels – 15 minutes.
- MRI of the mammary glands – 30 minutes.
- MRI of the abdominal cavity – 40-45 minutes.
- MRI of the lumbosacral spine - 15 minutes.
- MRI of the thoracic spine - 15 minutes.
- MRI of the cervical spine - 15 minutes.
- MRI of the pelvic cavity – 40 minutes.
- MRI of the bladder - 35 minutes.
During the examination, you must remain completely still. This should be taken into account in patients with severe pain. If, due to severe pain, it is not possible to remain in a forced position for a long time, then before the study it is necessary to perform seek pain relief from your doctor or come for an examination after relief of acute pain. If necessary, MRI is performed under sedation with the assistance of an anesthesiologist.
After MRI examination
A written conclusion and a computer disk with the obtained images are issued to the patient on the day of the examination. In the pictures, areas of healthy tissues differ from those in which any changes occur, but interpret the images and give based on them, only a specialist can provide certain recommendations for further actions. After examination, based on the results of the scan, the doctor may recommend to consult by a neurologist, traumatologist, surgeon, urologist, gynecologist, etc. The final diagnosis is made your doctor and prescribes the appropriate treatment according to him.
