MRI (magnetic resonance imaging) is a modern kind of diagnostics using a magnetic field and radio waves (but not ionized radiation, which is used in X-ray machines and computed tomography). Therefore, MRI is safe and can be performed as often as necessary. Magnetic resonance imaging is a highly informative diagnostic method, the most indicative for examination of soft tissues, allowing obtaining images in form of tissue sections of one or another organ.
Computed tomography (CT or MSCT) is a diagnostic technique based on the sectional examination of the internal organs and systems structure; the data are obtained by means of X-ray equipment combined with a powerful computer station, which allows for rapid detailed image analysis. Computed tomography is one of the best non-invasive (performed without tissues damage) diagnostic techniques.
The high-resolution capability of MSCT combined with advanced software that allows reconstruction of very thin sections, visualizes changes that do not exceed even a few millimeters in size, which allows detection of diseases at very early stages.
X-ray radiology is a field of medicine related to radiological methods of diagnosis of diseases. This examination is performed on modern diagnostic devices with the use of radiation.
