Barium swallow. Little or no preparations are required for the study of the larynx, pharynx, and esophagus when studied alone. A thick barium mixture is swallowed in supine position and fluoroscopic images of the swallowing process are made.
Depending on the organs to be examined, barium radiographs can be classified into barium swallow, barium meal, barium follow-through, and enteroclysis (small bowel enema). To further enhance the quality of images, air or gas is sometimes introduced into the gastrointestinal tract in addition to barium, and this procedure is called double-contrast imaging. In this case the gas is referred to as the negative contrast medium.
