What is a double-contrast barium enema?

ANSWER

During this test, your doctor injects a white liquid called barium into your rectum and then takes X-rays. The barium creates a clear picture of your colon so your doctor can spot any polyps. You'll have to prep for this test the same way you do for a colonoscopy.

If you decide you want to use this test to look for polyps, you'll likely need to get them every 5 years.
