摘　　要：目的 :评价MRI动态增强扫描联合常规MRI扫描对肛瘘的诊断价值。方法 :51例肛瘘患者行常规MRI扫描及动态增强扫描,比较肛瘘内、外瘘口的显示率及瘘管动态强化曲线。结果:MRI动态增强扫描共显示瘘管70个、内口51个、外口52个、脓肿9个;与手术所见比较,显示肛瘘内口、瘘管数量、肛瘘外口和脓肿准确率分别为96.2%、98.3%100.0%和100.0%,79.3%的瘘管强化峰值为165 s。结论:MRI动态增强扫描能提高肛瘘合并肛周脓肿的检出率,并对瘘管炎症活动性的判定有应用价值。Objective：To evaluate the value of dynamic contrast-enhanced MRI combined with routine MRI scanning for the diagnosis of anal fistula. Methods：A total of 51 cases were confirmed by postoperative anal fistula underwent routine MRI scanning and dynamic contrast enhanced MRI（DCE-MRI） examination,and the display rates of anal inner and outer fistula,dynamic enhancement curve were compared. Results：Compared with the operative findings,contrast enhanced MRI represented 70 fistulae （96.2%）,51 internal openings （98.3%） and outside mouth 52 （100%） as well as 9 sites of abscess （100%）,79.3% of the fistula peak enhancement for 165 seconds. Conclusion：Dynamic contrast enhanced magnetic resonance imaging can improve the detection rate of anal fistula. It is a feasible method for evaluating perianal fistula activity.
