X-rays can be used to look at the digestive tract by using liquid barium as a contrast agent (dye).

Barium is a heavy and dense white liquid with no flavour and a chalky texture. It shows up white on x-rays because of its high density (like bones).

Barium studies are mainly used to look at the gastro-intestinal (GI) tract, including the oesophagus, stomach, small and large bowel.

Usually, barium is given as a drink under the supervision of a radiologist. In order to see the large bowel, the barium is inserted into the rectum using an enema tube.

For most of these studies, a radiologist will be present. The radiologist uses an x-ray machine and live video to assess what is happening with the x-rays and dye in real-time.
