Magnetic resonance imaging is one of several methods used to reveal the body's internal structures and functions for research and diagnostic purposes. Through the use of a strong magnetic field and radio pulses, MRI technicians can create detailed images of tissues throughout the body. It's especially useful for soft tissues concealed by bones and other dense tissues, in areas such as the brain and joints.
The MRI scanner is a magnet shaped like a donut with a tunnel in the middle of the equipment. After the patient is arranged on a table, the table moves into the tunnel. As the patient rests inside the tunnel, radio waves are used to take pictures of the internal body.
