(barium follow-through) a technique for examining the small bowel, often used when small-bowel enema is not tolerated. The patient swallows dilute barium sulphate suspension and then a series of abdominal radiographs are taken. It is important that barium reaches the caecum for a complete examination. The technique is particularly useful for showing inflammatory bowel disease, particularly Crohn’s disease.
