摘　　要：目的:评价DWI联合常规MR扫描对肛瘘的诊断价值。方法:选取20例临床怀疑肛瘘或有肛瘘手术史患者行常规MR扫描及DWI检查,比较肛瘘内、外瘘口,瘘管分支及脓肿的显示率。结果:常规MR扫描序列共显示瘘管22个、内口14个、外口22个、脓肿14个;DWI检查共显示瘘管25个、内口16个、外口23个、脓肿17个。结论:DWI联合常规MR扫描可提供肛瘘合并肛周脓肿的检出率,为外科手术提供可靠的影像学依据。Objective：To explore the value of DWI combined with routine MR sequence for the diagnosis of anal fistulaMethods：20 patients with suspected anal fistula were examined with routine MR sequence and DWI,and the display rates of anal inner and outer fistula,fistula branch and abscesses were compared.Results：Routine MR sequence displayed fistula 22,inside mouth 14,outside mouth 22,abscesses 14;DWI displayed fistula 25,inside mouth 16,outside mouth 23,abscesses 17.Conclusion：DWI combined with routine MRI is a sensitive diagnostic method for anal fistula examination,it can provide important informations about anal fistula.Especially it can improve the detection rate of fistula combined with perianal abscess.
