The lower gastrointestinal series is also called Barium enema. It is a procedure used to examine and diagnose problems related to the large intestine. Barium sulfate is given to the person via an enema which fills the colon. Then the digestive system is examined through an X-ray. Barium sulfate is the radiocontrast agent which increases the visibility of internal structures using computing tomography. The procedure is used to diagnose bowel health and diseases like Crohn's disease, diverticulosis, and ulcerative colitis, etc.
