Leukocyte scintigraphy is a noninvasive imaging technique that quantifies inflammation. This technique can differentiate Crohn's disease from ulcerative colitis, it could potentially verify the presence of abscesses and fistulas, and has the advantage over endoscopy and radiology of being able to assess the colon and small intestine on the same occasion. Until now, however, leukocyte scintigraphy of the small bowel has not been compared with laparotomy plus intraoperative enteroscopy—the gold standard for detecting manifestations of Crohn's disease.
