Magnetic Resonance Imaging (MRI)

Test Overview

Magnetic resonance imaging (MRI) is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. In many cases, MRI gives different information about structures in the body than can be seen with an X-ray, Opens dialog, ultrasound, Opens dialog, or computed tomography (CT) scan, Opens dialog. MRI also may show problems that cannot be seen with other imaging methods.

For an MRI test, the area of the body being studied is placed inside a special machine that contains a strong magnet. Pictures from an MRI scan are digital images that can be saved and stored on a computer for more study. The images also can be reviewed remotely, such as in a clinic or an operating room. In some cases, contrast material, Opens dialog may be used during the MRI scan to show certain structures more clearly.

There are two main types of MRI—the standard MRI machine, Opens dialog and the open MRI machine, Opens dialog.
