Real time X-ray studies utilizing iodine contrast material to help demonstrate normal anatomy as well as abnormalities of the gastrointestinal tract, renal tract and uterus.


Hysterosalpingogram (HSG) is the study of the uterus and fallopian tubes whereby iodine contrast is injected through the cervix into the uterus. It shows whether the uterine cavity is normal and if the fallopian tubes are open. This is usually part of the fertility work-up.

Barium Swallow

The patient is given barium to drink and then x-rays are taken of the oesophagus (food pipe) as the contrast moves down to the stomach. This test is requested in the investigation of dysphagia/odynophagia(pain and difficulty in swallowing), reflux disease, benign and malignant oesophageal strictures, and following ingestion of foreign bodies.



Barium Meal

Similar to the barium swallow, but the focus is on the stomach. The barium coats the walls of the stomach and can demonstrate ulcers, gastritis and cancers.

Barium Enema

Barium is injected through the rectum so that the entire colon is filled. The enema is used in order to find colon cancer, diverticular disease and polyps.
