A barium X-ray, also known as a barium swallow or barium enema, is a specialized radiographic imaging technique used to visualize the digestive tract. It involves the administration of a barium sulfate contrast medium, which coats the lining of the esophagus, stomach, or intestines, making these structures more visible on X-ray images. This diagnostic tool is particularly useful for detecting abnormalities such as tumors, strictures, and other structural changes that may indicate cancer.
