MRI (magnetic resonance imaging) is a method of imaging organs and tissues based on the use of a powerful magnetic field.

In action, it looks simplified like this: each tissue of our body has its own composition, contains hydrogen atoms in different forms and quantities. Magnetic resonance imaging is a huge electromagnet. Under the influence of its magnetic field, we can visualize hydrogen atoms in tissues, they become visible as a kind of "beacons". The device will record them and create an image of the tissues layer by layer based on this data. So in the end, we will get both individual layer-by-layer images and 3D images of organs.

 

What is the difference between CT (computed tomography) and MRI?

We have understood a little about MRI - it is a visualization of the energy of hydrogen protons in tissues under the influence of a magnetic field.

So what is a CT scan? After all, the principle is the same - we get a multi-layered image of fabrics...

During CT, instead of a magnet, an X-ray tube is used. X-rays from it pass through the tissues of the body at different speeds and are delayed in them in different ways. Soft tissues pass the ray quickly, it is almost not delayed in them, and hard and dense (bones) - slowly.

From these differences, we get the following advantages of MRI:

  • safety (it is possible to conduct research on pregnant women, starting from the second trimester, and children, and repeatedly do control examinations, because there is no ionizing radiation);
  • high informativeness due to the presence of soft tissue image contrast (different amount of hydrogen in tissues allows visualization of ligaments, articular apparatus, cartilage tissue, spinal cord, etc. in separate colors);
  • high image quality and diluting ability (allow to detect even minor deviations from the norm, i.e. to diagnose the disease in the initial stages).

All these advantages allowed MRI to find wide application in medicine. 

MRI is used daily to diagnose diseases of the brain and spinal cord, parenchymal organs of the abdominal cavity (liver, pancreas), pelvic organs, and the endocrine system. 

In addition, MRI is the "gold standard" for musculoskeletal diagnostics. And the high resolution and contrast of the image of soft tissues in some cases make it possible to see the pathology of the cerebral vessels even without the introduction of contrast.

You can get an MRI in Kyiv on a doctor's referral or by self-referral: https://dr-spin.com/ru/sdelat-mrt-v-kieve/.

MRI has a narrow list of contraindications, most often they are associated with the presence of metal structures and electronic equipment in the patient. The magnetic field can contribute to the heating and movement of metal elements (tissue injury) or to the failure of mechanisms. In addition, there will be a fuzzy image in the area of ​​metal structures.

Be sure to tell your doctor if you have an artificial pacemaker, implants, had a joint replacement, or have any other metal components. If an MRI is not possible, the doctor will advise you of an alternative research method.
