X-Ray - Barium Swallow/Meal Examination
A barium swallow images the oesophagus. A barium meal images the stomach. These tests are often performed together. You will swallow about a cup of barium liquid. A thin coating of a barium compound lines the inside of the oesophagus and/or stomach, and x-rays are taken. Barium appears white on the x-ray image and outlines any irregularity of the internal walls of the oesophagus and/or stomach.
