Barium Swallow: MedlinePlus Medical Test
What is a barium swallow?
A barium swallow, also called an esophagogram, is an imaging test that checks for problems in your higher GI tract. Your higher GI tract involves your mouth, back of the throat, esophagus, tummy, and initially component of your tiny intestine. The test works by using a unique style of x-ray called fluoroscopy. Fluoroscopy displays internal organs going in true time. The test also requires ingesting a chalky-tasting liquid that is made up of barium. Barium is a compound that makes elements of your physique exhibit up more obviously on an x-ray.
