Patients suffering from inflammatory bowel disease (IBD) require prompt and accurate treatment in order to relieve their symptoms and to minimize potential complications. Conventional enteroclysis (CE) has been considered to be the imaging technique of choice for evaluating the small bowel. Adequate distension is mandatory because collapsed bowel loops may hide or even simulate small bowel disease. However, CE provides no information on extralumenal disease extension and does not allow any determination of disease activity. The modalities for diagnostic imaging in IBD have dramatically changed over the past decade. Large bowel enemas have lost their importance compared to colonoscopy, and conventional enteroclysis has been widely replaced by CT-and MR enteroclysis (CTE, MRE).
