This test involves filling the esophagus, and to a lesser extent the stomach and small intestine, with barium solution. Barium is a white, chalky substance that illuminates on an X-ray image. The barium defines the anatomy of the upper digestive tract, which is also known as the upper gastrointestinal (GI) series. An esophagram takes roughly 20 minutes.
