摘　　要：目的：分析小肠克罗恩病的MRI表现,并与小肠钡灌肠进行了比较.方法：回顾性分析了2001年1月～2004年5月间临床拟诊克罗恩病的患者共35例.所有患者均接受了小肠钡灌肠和MRI检查.分别计算和测量病变累及的肠段数、肠壁厚度、狭窄点.分辨肠壁信号特点、溃疡、瘘道、脓肿、系膜改变等情况.MRI和小肠钡灌肠的符合率包含了病变肠段和无病变肠段的一致性.结果：MRI和小肠钡灌肠检出病变肠段的符合率为90.8%.采用配对资料卡方检验,χ^2=0.364,P＞0.05.SE-T1W、SE-T2W、SPIR-T1W、SPIR-T2W发现病变肠段数占MRI总检出肠段数的比率分别为50.0%、100%、48.1%、88.5%.结论：MRI和小肠钡灌肠所显示的病变肠段基本一致,SE-T2W的检出率最高.Objective： To evaluate the value of the MR imaging of the small-bowel Crohn＇s disease and compare it with small-bowel enteroclysis.Methods： Thirty five cases from Jan 2001 to May 2003 were analyzed retrospectively. All the patients were examinated with small-bowel enteroclysis and MR imaging. We measure the number of the intestinal segment being involved, the thickness of intestinal wall and the intestinal stenosis. We distinguish the signal characteristic of intestinal wall, ulcer , fistula, abscess and mesentery. The coincidence rate means the concordance between MR imaging and small-bowel enteroclysis in finding the affected intestinal segment. Results： The coincidence rate is 90.8%（X^2 = 0.364, P 〉 0.05）. The detectable rate of the sequence of SE-T1W,SE-T2W,SPIR-T1W,SPIR- T2W is 50.0% ,100% ,48.1% ,88.5%. Condusion： It is identical between MR imaging and small-bowd entereclysis in finding affected intestinal segment. The detectable rate of SE-T2W is highest.
