Computed tomography enterography

CT imaging of the small bowel using oral contrast.

Last updated 5 November 2026

CT enterography (CTE) is a small bowel imaging method that combines a CT scanner with oral contrast material. First described in 1997 by Raptopoulos and colleagues, it is primarily used to detect and evaluate the severity of Crohn's disease. It differs from CT enteroclysis, which delivers contrast via a nasojejunal tube.

Did You Know?

CT enterography should not be confused with CT enteroclysis, in which contrast is administered through a fluoroscopy-guided nasojejunal tube.
Many findings of Crohn's disease on CTE can be caused by a wide variety of other conditions.
