Introduction

Abstract

Since the small bowel except the duodenum and terminal ileum is largely inaccessible during endoscopic examination, radiology of the small bowel attains special significance as a diagnostic method. Owing to the length and position of this organ, good images are difficult to obtain. Furthermore, the considerable variation of transit time, unpredictable response of the contrast medium, and superimposition with the filled loops make small bowel radiology difficult. As a result, few radiologists specialize in this field. With the exception of Crohn’s disease, disorders of the small bowel are relatively rare. Thus, not many clinicians and radiologists are interested in the small intestine.
