In modified barium swallow, you ingest foods and liquids containing barium sulfate, a contrast dye that sharply outlines your mouth, throat, and esophagus on x-ray film. Using real-time x-rays, or fluoroscopy, a physician and a speech pathologist observe the movement of the barium through these structures on a television monitor.
