barium x-ray

Description

A procedure used to x-ray the esophagus, stomach, small intestine or large intestine. A contrast medium (barium) is used to make organs and structures show up clearly on the x-ray image.

Doctors use barium x-ray to look for tumours, polyps, blockages or other signs of disease.

A barium enema is used to inject barium into the colon and rectum through the anus. A barium swallow or barium meal is used to coat the esophagus, stomach and duodenum (the first part of the small intestine) with barium.
