Barium Enema IntroductionA barium enema is a diagnostic test. During the test, the doctor puts a contrast material called barium into the rectum. Enough barium is given to fill up the colon (large intestines). A plain x-ray of the abdomen is then taken. By filling the entire cavity of the colon, the doctor can see the contour of the colon's lining. Polyps, diverticula (outpocketings), ulcers, fistula (openings), crypts (certain types of cavities), and inflammatory changes can be detected. Masses (such as tumors) are specifically of interest because this test is often used to screen for colon cancer.
