Barium Swallow: MedlinePlus Medical Test

What is a barium swallow?

A barium swallow, also called an esophagogram, is an imaging test that checks for complications in your upper GI tract. Your upper GI tract contains your mouth, back again of the throat, esophagus, belly, and initial portion of your small intestine. The test utilizes a unique form of x-ray called fluoroscopy. Fluoroscopy demonstrates interior organs going in true time. The test also consists of consuming a chalky-tasting liquid that consists of barium. Barium is a substance that tends to make sections of your entire body demonstrate up more clearly on an x-ray.
