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.
The time to get ready and the test itself may take 2 to 3 hours. You may spend 15 to 30 minutes inside the machine.
If you breastfeed and are concerned about whether the contrast material used in this test is safe, talk to your doctor. Most experts believe that very little dye passes into breast milk and even less is passed on to the baby. But if you are concerned, you can stop breastfeeding for up to 24 hours after the test. During this time, you can give your baby breast milk that you stored before the test. Don't use the breast milk you pump in the 24 hours after the test. Throw it out.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. Ask your doctor when you can expect to have your test results.
