密执安大学的研究人员开始用同位素标记自体白细胞鉴别痉挛性结肠炎与溃疡型或肉芽肿样结肠炎。内科和放射学副教授Jerry Froelich在北美放射学会上报告称,采用此新方法时,门诊病人不需要作胃肠方面的准备工作;新方法较结肠镜检查舒适,而且与钡餐检查比较,照射量明显减少。Froelich说,~111铟8-羟基喹啉(Oxine)标记白细胞能够对病人进行诊断,对病变部位进行定位,鉴别局灶型的病变抑或是扩散型的病变及其严重程度的分级。对于已经证实有溃疡或肉芽肿样结肠炎的 Researchers at Michigan University began using isotope-labeled autologous leukocytes to identify spastic colitis and ulcerative or granulomatous colitis. Jerry Froelich, associate professor of internal medicine and radiology, reported at the North American Society of Radiology that out-patient patients do not need to be prepared for gastrointestinal use using this new method; the new method is more comfortable than a colonoscopy and shows significantly greater exposure to barium meal cut back. Froelich said ~ 111 indium 8-hydroxyquinoline labeled leukocytes are capable of diagnosing patients, locating the lesion, identifying focal lesion or diffuse lesion, and grading of its severity. Has been confirmed for ulcers or granulomatous colitis
