What is Magnet resonance imaging (MRI)?
Using magnet resonance imaging, or in short MRI, we can take anatomical and functional images of the human body. This way bones, muscles, tendons, ligaments, joints, vessels, organs and even metabolic processes or chemical compositions can be analyzed. Unlike X-ray technique, no radioactive radiation is necessary to create the images. The MRI scanner works with a magnet and sending and receiving coils. The magnet and the radiofrequency coils activate hydrogen atoms in a way that they give a special resonance to be measured by the receiving coils. Based on the received information, an anatomical MR image is created by powerful computer systems compiling the single layer data into a complex three-dimensional image. Subject to the examination area, receiving coils are placed directly onto the corresponding area. If you want to examine the head, you have to surround the head by a coil. If you want to analyze a knee, a special coil around the knee is used etc. Averagely, an MRI examination last about 20-40 minutes.
