Barium follow-through
From Wikipedia, the free encyclopedia
A barium follow-through procedure is a type of medical imaging technique. It is used to evaluate the presence of disease in a person's small intestine.
The person under investigation drinks a contrast medium containing barium sulphate. This contrast medium appears white on x-rays, and shows the outline of the internal lining of the bowel.
X-rays are taken as the contrast moves through the intestine, commonly at 0 minutes, 20 minutes, 40 minutes and 90 minutes. A later x-ray may also be taken to examine the terminal ileum.
