Отличие КТ от МРТ? Разбираемся вместе.

Roman Titorenko, the chief physician of Mediscan Group, helped us understand the difference between CT and MRI Mediscan https://mediscangroup.com.ua/ A computer tomograph (CT) is an X-ray examination method. It consists of 3 basic units: a gantry, inside which there is an X-ray tube on one side and detectors on the other. This entire system rotates around the patient and produces images. When an X-ray passes through the human body, it weakens, depending on what tissues, this information is transmitted to a powerful computer - which reconstructs the image based on this information. Magnetic resonance imaging (MRI) is an "assembly" of a very powerful magnet and radio, inside the magnet - all the atoms line up in one direction, then radio frequency pulses are produced along them. When an atom deflects, it emits a return signal - which is captured by special coils, on the basis of which the image is reconstructed on the computer. What are slices in CT - this is the number of rows of detectors in the gantry tube. The difference in images does not directly depend on the number of slices. The main difference is the scanning speed and patient comfort. A large number of slices makes it possible to give CT of the heart. What is TESLA in a tomograph - this is the power of the magnetic field, and the larger the field, the better the study. A powerful field allows you to "line up" atoms more clearly. Most often, CT is used in oncology. These are abdominal organs and lungs. Also ENT organs and traumatology. MRI is more often used in the diagnosis of the brain, spine. Also - joints, muscles. Also MRI is the gold standard in the diagnosis of pelvic organs - prostate, gynecology, rectum With computed tomography, there is a fairly serious radiation load, which is completely absent with MRI. Strengths: For CT, there are almost no "blind spots" during the study. CT scans can take 1-2 minutes, and MRIs can take 30 minutes MRIs cannot be performed on patients with electronic devices inside the person (pacemakers, pumps, etc.)
