Indium-111 autologous leucocyte scanning: comparison with radiology for imaging the colon in inflammatory bowel disease.

Abstract

Indium-111 autologous leucocyte scanning was compared with barium enema for assessing the extent of colonic disease in Crohn's colitis and ulcerative colitis. Scanning was shown to be as accurate as conventional radiology in colitis, reliably distinguishing active from inactive disease. The results suggest that 111In-leucocyte scanning is an accurate, non-invasive, alternative technique for imaging the extent of disease in colitis.
