Lower GI Tract Examination/Barium Enema
Contact UsOur Procedures
Lower Gastrointestinal Tract Radiography(barium enema) is a dynamic fluoroscopic x-ray evaluation of the large intestine, also known as the colon. This includes the right or ascending colon, the transverse colon, and the left or descending colon and the rectum. The appendix may be seen if it is present and a portion of the small intestine may be visualized as well.
In this procedure a small amount of barium and air are introduced into the rectum so that the colon can be gently distended in order to visualize all structures.
Fluoroscopy uses x-rays to capture an image of an organ and control the amount of barium and air that is introduced.
