Barium is a chemical element with symbol Ba and atomic number 56. It is the fifth element in Group 2, a soft silvery metallic alkaline earth metal. Because of its high chemical reactivity, barium is never found in nature as a free element. The hydroxide, known in pre-modern history as baryta, does not occur as a mineral, but can be prepared by heating barium carbonate.
A barium enema is also called a lower GI (gastrointestinal tract) series or lower GI tract radiography. It makes still pictures as well as moving images. It uses a special type of X-ray called fluoroscopy. The procedure involves putting barium inside the colon through a tube inserted into the rectum. Barium is a chalky metallic contrast material. It illuminates the colon to show detailed images of the inside of the colon. A barium enema is only one method used to diagnose colon conditions.
