It is the gold standard for evaluating small bowel diseases like Crohn's. CT enteroclysis is now available which combines the advantages of CT (ample extraluminal information and visualization) and conventional enteroclysis (distension of small bowel for visualization). A report (Am J Roentgenol. 2005;185:1575-1581) suggested CT enteroclysis to be superior to conventional enteroclysis in evaluation of symptomatic Crohn's disease, especially for the detection of fistula, abscess, skip lesions, lymphadenopathy, and conglomeration of small bowel loops.
