MRIskannausta

MRIskannausta, also known as magnetic resonance imaging (MRI), is a non-invasive medical imaging technique used to create detailed images of the internal organs and structures of the body. It utilizes strong magnetic fields and radio waves to generate these images, without the use of ionizing radiation like X-rays. The process involves placing the patient within a large, powerful magnet, where radio waves are then pulsed through the body. Different tissues respond to these radio waves in distinct ways, and these responses are detected by a scanner. A computer then processes this information to construct cross-sectional images.

MRI is particularly useful for visualizing soft tissues such as the brain, muscles, ligaments, and tendons, making it invaluable for diagnosing a wide range of conditions. It can detect abnormalities like tumors, inflammation, injury, and degenerative diseases. The procedure is generally painless, although some individuals may experience claustrophobia due to the confined space of the MRI scanner. It is important to inform the medical staff of any implanted medical devices, such as pacemakers or certain types of metal prosthetics, as the strong magnetic field can interfere with their function. The entire scanning process typically takes between 15 to 90 minutes, depending on the area of the body being examined and the specific sequences used.
