X-rays can be used to look at the digestive tract with the aid of liquid barium used 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.
Barium is predominantly introduced to the body by drinking it from a small cup under the supervision of a Radiologist. However, to assess the large bowel the barium is introduced to the rectum using an enema tube.
For most of these studies a Doctor (Radiologist) will be present for part of the study. The Radiologist uses an X-Ray machine that uses live video to assess what is happening with the X-Rays and dye in real time.
