Gastrointestinal Radiology and Specialized Radiology

Gastrointestinal and colon tests

These radiological tests show the digestive system organs in order to evaluate their function and detect any abnormalities such as: ulcers, inflammation of the intestinal walls, tumours, reflux, hernias, polyps, etc. A tube fitted with a conventional x-ray apparatus is used to create the images showing the organs in action. An appointment is needed for this type of testing.

Preparation

The preparation required depends on the type of test requested by your doctor. Each one has its own specific requirements.

Barium swallow esophagus/and or small intestine

It is important not to have anything to eat or drink after 8:00 p.m. the evening before the test. The morning of the test, do not drink water, smoke, or chew gum. You can take your regular medication with just a bit of water. When you make your appointment, it is important to mention if you are diabetic.

Procedure

You will be asked to put on a gown and to take off any metal objects that may interfere with the test. You will be asked to drink barium and swallow some small crystals. The barium is a white liquid, with a slight vanilla or strawberry flavour. This liquid coats your digestive system organs making them visible. The amount you need to drink depends on the type of test, or the organ being examined. The crystals will produce gas in your stomach to make your organs more visible. You digestive system will be examined from several angles and you will be asked to take several different positions (standing up or lying down) in order to ensure that all of your organs have been examined properly. As well as looking at your organs in action, some static x-rays will be taken for analysis once the test is complete. This test usually takes 20 minutes. However, tests of the small intestine depend on how quickly your digestive system works (usually from 60 to 240 minutes). Tests of the digestive system are painless and have no side effects. 

Digestive x-ray tests are usually covered by the RAMQ.
