Barium sulfate suspension - Wikipedia

Barium sulfate suspension, often simply called barium, is a contrast agent used during X-rays. Specifically it is used to improve visualization of the gastrointestinal tract (esophagus, stomach, intestines) on plain X-ray or computed tomography. It is taken by mouth or used rectally.. Side effects include constipation, diarrhea, appendicitis, and if inhaled inflammation of the lungs.
