CT enterography: state-of-the-art CT technique for small bowel imaging

Abstract

Multi-detector computed tomography has become a first-line imaging modality for the evaluation of small bowel disease. Its high speed and resolution ensure excellent imaging of the small bowel with simultaneous evaluation of the lumen and wall, adjoining mesentery, and extraluminal structures in the abdominal cavity. Optimal luminal distension is an important prerequisite. Computed tomography enterography (CTE) is a dedicated adaptation for the study of the small bowel. This review discusses CTE with emphasis on procedural technique and image interpretation.
