Small bowel imaging: CT enteroclysis or barium enteroclysis? Critically appraised topic.

Barium enteroclysis has been traditionally used in the diagnosis of small bowel Crohn's disease. Recently CT enteroclysis has been developed as an alternative imaging technique for small bowel Crohn's disease. A search and critical appraisal of the literature was performed to determine which technique is better for diagnosis of Crohn's disease. The best current evidence indicates that CT enteroclysis is a good test for the diagnosis of Crohn's disease but barium enteroclysis may also be required in a small group of patients.
