A special x-ray of the colon that visualizes the entire large bowel. A liquid barium is given by enema to coat the large intestine and make it visible by x-ray. In some cases air is mixed with the barium as well.

Exam Time: 30-45 minutes

It is recommended that fluids be increased for the remainder of the day following the barium enema to help the body completely evacuate the residual barium.
