How the Test is Performed?
Before the x-rays are taken, you must drink 16 – 20 ounces of a milkshake-like drink that contains a substance called barium, which shows up well on x-rays.
An x-ray method called fluoroscopy tracks how the barium moves through your esophagus, stomach, and small intestine. Pictures are taken with you in a variety of positions. You may be sitting or standing.
The test usually takes around 3 hours. However, in some cases, it may take up to 6 hours to complete.
How to Prepare for the Test?
Usually, you cannot eat for a period of time before the test. You will be asked to remove all jewelry on your neck, chest, or abdomen before the test.
