Specialty-trained gastrointestinal radiologists offer CT and MR enterography to evaluate the small intestine. CT and MR enterography are noninvasive, safe procedures that use both intravenous and oral contrast to create detailed images of the small bowel.
These procedures use the cross-sectional imaging technology of computed tomography or magnetic resonance to assess the small intestine, the surrounding mesentery, vasculature and other adjacent structures.
- To evaluate known or suspected inflammatory bowel disease, including Crohn’s disease
- To determine an etiology for occult gastrointestinal bleeding
- To assess small bowel lesions
CTE and MRE are especially well-suited for patients with inflammatory bowel disease such as Crohn’s disease. A single test may determine the status of the disease and also assess for complications including abscess, fistula, or obstruction. In addition, follow up studies may be performed to assess for response to treatment. These procedures may also be indicated for occult gastrointestinal bleeding or to assess for focal small bowel pathology. The bowel wall is well appreciated with CTE and MRE so that tumors within the intestinal wall may be identified, including lesions that may not be visible within the bowel lumen with standard endoscopy or capsule endoscopy.
