BARIUM ENEMA

A barium enema, also known as a lower gastrointestinal (GI) exam, uses X-ray and a contrast material to capture images of the large intestine, which includes the colon and rectum. The test is used to detect disease or other problems.

There are two types of barium enemas, a single contrast study and an air-contrast study. A single-contrast study fills the

What should I expect?

During the exam, the colon is filled with a contrast material containing barium. The use of barium causes colon to show up clearly on the X-ray images.

In an air-contrast study, the colon is first filled with barium and then drained shortly after, leaving a thin layer of barium on the wall of the colon. The colon is then filled with air, providing a detailed view of the inner surface of the colon. The test is best to see colon polyps, colorectal cancer or inflammation.

How do I prepare for the exam?

It is essential that your intestine be thoroughly cleansed before your exam. Even a small amount of stool within the intestine can hide abnormalities. Inland Imaging will provide you with a preparation kit prior to your exam. This kit will contain laxatives and a suppository.
