a radiographic (x-ray) examination of the upper gastrointestinal (GI) tract, specifically the pharynx (back of mouth and throat) and the esophagus (hollow tube of muscle extending from below the tongue to the stomach)
A diagnostic technique to "see" a tumor in the digestive system. A series of x-rays is taken after the patient swallows liquid barium. Barium coats the surface of the digestive tract and helps create a good picture.
An x-ray study of the portion of the digestive canal between the throat and stomach (esophagus) in which the patient swallows a barium mixture while the x-ray doctor watches for signs of narrowing, irregularity, or blockage. No preparation is required except fasting. Sometimes, in a procedure called an upper gastrointestinal (UGI) series, the barium is also observed after it enters the stomach to check for stomach problems or ulcers.
(also GI series; upper GI series) - The purpose of the test is to detect abnormalities of the esophagus, stomach, and small intestines. This test may be done in an office or a hospital radiology department. More Information
