Barium Enema is an x-ray examination of the large intestine, also known as the colon. This includes the right or ascending colon, the transverse colon, the left or descending colon and the rectum. The appendix and a portion of the small intestine may also be included. A special form of x-ray called fluoroscopy is used to visualize a contrast material called barium within the colon. Fluoroscopy makes it possible to see internal organs in motion. When the lower gastrointestinal tract is filled with barium, the radiologist is able to view and assess the anatomy and function of the rectum, colon and part of the lower small intestine
