A few minutes after registering, a member of our team will escort you to the changing room where you will put on an exam gown.
You will then be led to the exam room where we will ask you to lie on a movable table. The technologist will inject a drug to reduce abdominal cramps. A white liquid (barium) with some air will be administered in the intestine through a small plastic tube inserted into the anus. It is normal to feel bloated. The technologist will monitor the progress of the liquid in the colon and take a series of images in various positions.
It is important to carefully follow the instructions in order to carry out the exam correctly and to ensure quality images.
After the exam, you may resume your regular activities. We recommend drinking plenty of water as barium can cause constipation. In the days following the exam, it is normal to find barium residue (white matter) in the stool.
The X-rays are reviewed by the radiologist after your departure. The final report is sent to your doctor within 24-48 hours.
- Arrive 15 minutes before your appointment
- Notify the technologist if you are pregnant or think you might be
- Bring your health insurance card (RAMQ)
