Barium enema (colon)
The barium enema is a real-time examination of your colon (or large intestine), under fluoroscopy. The radiologist injects a contrast agent and air in your rectum with a small flexible tube.
It captures images of your large intestine in movement in order to:
- Conduct a follow-up evaluation after a positive result on a fecal occult blood test (FOBT)
- Check for the presence of polyps or masses in the large intestine
- Find the cause of bleeding, nutrient absorption problems, or abdominal pain linked to the intestine
- Diagnose cancer or other lower digestive tract disorders
During the procedure, the technologist:
- Will use a small lubricated plastic tube to inject a contrast agent and a small amount of air in your rectum
- Will ask you to adopt certain positions (standing or lying down, face up or face down) to get a clear view of all your organs
- Will capture dynamic and static images
Please note that the total duration of your visit for this examination can be between 60 and 90 minutes, even though the examination procedure itself will only last between 30 minutes.
