Mr enterogram

A magnetic resonance (MR) enterogram is a test that uses a magnetic field and pulses of radio wave energy to make pictures of your small intestine. It's a type of magnetic resonance imaging (MRI).

When you have this test, you lie on a table. The table moves into the MRI machine. The machine takes pictures, which are reviewed on a computer in another room. This test isn't an X-ray. No radiation is used.

An MR enterogram lets your doctor see the lining of your small intestine. It can help your doctor look for causes of swelling, blockages, and bleeding when the results of other tests are not clear.

• A tube called an I.V. may be put into your arm. The I.V. may be used to give you fluids and medicine. This may include medicine to keep your bowel still to allow better pictures. During the test, more dye may be added through the I.V.
• You will lie on a table that's part of the MRI scanner.
• The table will slide into the space that contains the magnet.
• Inside the scanner, you will hear a fan and feel air moving. You may hear tapping, thumping, or snapping noises. You may be given earplugs or headphones to reduce the noise.
• You will be asked to hold still during the scan. You may be asked to hold your breath for short periods.
• You may be alone in the scanning room. But a technologist will watch through a window and talk with you during the test.

• You may be asked to not eat or drink for several hours before the test.
• Tell your doctor if you get nervous in tight spaces. You may get a medicine to help you relax. If you think you'll get this medicine, be sure you have someone to take you home.
