+The exam

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 you will be asked to drink a white liquid (barium, which has a light vanilla taste). A radiologist will ask you to take different positions for a series of images.

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.
