Abstract
CT enterography (CTE) is a noninvasive imaging test using neutral intraluminal contrast and intravenous contrast to evaluate the small bowel. Multiphasic imaging is used in evaluating obscure gastrointestinal bleeding (OGIB), and single-phase enteric imaging is used for all other indications, including Crohn's disease (CD). CTE findings of CD include bowel wall thickening, mucosal hyperenhancement, and mural stratification. CTE findings of angiodyplasias include a vascular tuft visible during arterial phase and an early draining mesenteric vein. Early studies indicate that CTE is superior to barium examination in the evaluation of CD and is complementary to capsule endoscopy in the evaluation of OGIB.
