【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。更多还原

【Abstract】 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.更多还原
