Magnetic Resonance Imaging (MRI) Of The Spine

Content provided by Healthwise

Test Overview

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

For an MRI test, your body 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 further study. The images also can be reviewed remotely, such as in a clinic or an operating room. In some cases, a contrast material may be used during the MRI scan to show certain structures more clearly.

The MRI can find changes from the normal in the spine and in other tissues. It also can find problems such as infection or a tumor. MRI can look at the spine in the neck (cervical spine), upper back (thoracic spine), or lower back (lumbosacral spine). The entire spine can be seen in one series of pictures to find a tumor. More detailed pictures of one area may be taken. See MRI pictures of the lumbar spine .

MRI may be used to check low back problems. For more information, see:
