Ultrasonic patterns in inflammatory bowel disease.

Ultrasound examination was performed in 90 patients with varying bowel pathology. Ultrasound reliably demonstrated thickening of the bowel. In addition, the pattern of abnormality seen in Crohn's disease and ulcerative colitis was different, and corresponded to the pathological changes seen in these disease processes. The pattern of bowel abnormality seen in other bowel diseases with an inflammatory aetiology generally corresponded to either the Crohn's or ulcerative colitic pattern. The appearances are described, together with findings in other non-neoplastic diseases of the bowel.
