Magnetic resonance imaging (MRI): An MRI uses a large magnet and radio waves to create images of the inside of your body. It’s especially useful in showing fistulas around your small intestine and anus. You may need to drink a special contrast fluid before the procedure to clarify the images (MRI enterography).
Endoscopy

An endoscopy sends a thin tube with a light and camera (endoscope) into your digestive tract to take images or show videos of areas with inflammation. You’ll be sedated for these procedures.

Colonoscopy: During this procedure, a provider uses an endoscope to examine the inside of your colon and lower small bowel (ileum). They may remove a tissue sample (biopsy) to test for white blood cells.
Upper endoscopy: A provider passes an endoscope through your mouth and into your throat. An attached camera allows your provider to see inside, from your mouth to the start of your small intestine.
Capsule endoscopy: You swallow a small plastic capsule with a light and a camera that takes pictures as it moves through your digestive tract.
