An MR enterography procedure uses magnetic resonance imaging (MRI) technology to obtain detailed images of the small bowel.

Participants will be given a low concentration of barium sulfate solution (1350 mL) prior to the MRI procedure. Barium sulfate is a radiopaque agent. Radiopaque agents are used to help diagnose certain medical problems. Since radiopaque agents are opaque to (block) x-rays, the areas of the body in which they are localized will appear white on the x-ray film. This creates the needed distinction, or contrast, between one organ and other tissues. The contrast will help the doctor see any special conditions that may exist in that organ or part of the body.
