A barium enema is an X-ray imaging test of the lower intestinal tract that uses a contrast solution containing the metallic element barium. The barium solution is delivered through the use of an enema, a process in which liquid is pushed into your rectum through your anus while a technician takes X-ray images of the area. Barium enhances the X-ray images by highlighting certain areas of tissue and allows the radiologist to see your internal organs in motion by tracking the flow of the barium solution through your intestinal tract.
