摘　　要：目的探讨磁共振肛瘘成像技术在术前分型诊断及预后评估的应用价值。方法对43例肛瘘患者于术前行MRI检查,根据图像判断内、外口的位置及瘘管的走行,为临床治疗及手术方案的制订提供影像学依据。结果磁共振肛瘘成像对于病变的检出敏感性较高(37/43)。对于大部分的肛瘘病例,均能较好的显示瘘管的走行情况及开口位置(32/37)。MRI分级与预后有良好的相关性。结论 MRI是目前用于肛瘘术前评估的最佳影像学方法。MRI可以准确显示病变范围、评估预后,有助于治疗方案的制定和疗效监测。Objective To discuss MRI manifestations and diagnostic value of anal ifstula.Methods MRI was performed in 43 patients with anal ifstula. MRI manifestations of the anal ifstulas that were compared with the operation results.Results 37 of anal ifstula were showed by MRI. We can tel the internal ostia and external ostia on MRI in 32 patients. Parks IV was seldom detected on MRI. The MRI ranks of anal ifstula have relevance with prognosis.Conclusion MRI can accurately detect the ifstula and abscesses of anal ifstula. MRI has clinical signiifcance in the auxiliary diagnosis and prognosis for anal ifstula. It is a useful diagnostic method for anal ifstula.
