[CT-enteroclysis]

Abstract

Computed tomography enteroclysis (CTE) has become a well-defined imaging modality for the evaluation of various small bowel disorders. The large volume (2 l) of enteral contrast agent administrated via a nasojejunal catheter ensures small bowel distension. Following helical CT acquisition is completed by multiplanar views. CTE is of particular value in intermediate or advanced Crohn's disease. It has become the method of choice for small bowel tumours. The cause and degree of low-grade small bowel obstruction is more readily analyzed with the technique of CTE than conventional CT. CTE should be selectively used to answer specific questions of the small bowel. It essentially contributes to the diagnostic quality of modern small bowel imaging, and therefore deserves an established, well-defined place among the other available techniques.
