What X-ray tests can be used to examine the digestive tract?

ANSWER

Colonoscopy is usually the preferred test to examine the lower digestive tract. However, there are several commonly performed X-ray tests that allow your doctor to examine your digestive tract from the esophagus to the rectum.

These tests use barium or an iodine-containing agent that allows a doctor to see the digestive tract and a form of X-ray machine called fluoroscopy. Fluoroscopy allows part of the body to be studied in motion and recorded on a video monitor.

These tests are called an "upper GI" or "lower GI," depending on the part of the digestive tract being examined.
