Magnetic resonance imaging (MRI) is a radiological study that obtains images with magnets and radio waves. Unlike X-rays and CT scans, MRI uses no radiation. There are three types of MRI machines: closed, open and standing. Closed and open are most commonly used. Closed MRIs are the oldest type of MRI machines. During the procedure, the patient lies down on a table, which slides into a large tube. The patient is asked to lie very still during the test.
