摘　　要：目的:探讨高分辨力MRI对肛周窦道及瘘管的诊断价值。方法:收集158例肛瘘患者,术前均行MRI检查,检查序列主要包括矢状面、冠状面快速自旋回波T_2WI、T_1WI及脂肪抑制PDWI,并比较影像学诊断与手术结果。结果 :158例肛瘘共183个原发瘘管,184个内口,171个外口,124个肛周脓肿。MRI对肛瘘原发瘘管,肛周脓肿及内口显示的灵敏度分别为95.6%,99.1%,93.1%。结论 :MRI可准确判断肛瘘的分型、瘘管走行、有无脓肿、支管形成,以及肛瘘内口的位置,为临床治疗提供重要信息。Objective：To evaluate the accuracy and clinical value of preoperative high-resolution magnetic resonance imaging for the diagnosis of anal fistula. Methods：Preoperative MRI examination was performed in all patients. MR scan sequences were contained such as the fast spin echo T2 WI at sagittal and coronal planes,and spin echo T1 WI,fast spin echo T2 WI and PDWI with fat suppression at axial plan. MRI findings were analyzed by comparing with the surgical results. Results：158 patients were found to have 183 primary fistulas,184 internal openings,171 external openings,and 124 perianal abscesses. Conclusions：MRI is accurate for the classification and primary fistula tracks anal fistulas,perianal abscesses and internal openings.
