Magnetic resonance imaging (MRI) of the anal canal was retrospectively evaluated during a three year period in 67 patients with suspected perianal fistulae. In six cases the surgeon, who knew the results of the MRI, found a fistula not seen on MRI while MRI showed a fistula in one patient which could not be found at surgery. We recommend MRI in cases where an experienced surgeon has difficulties mapping the fistula tract.
在三年期间，对67例疑似肛周瘘管的患者进行了肛管磁共振成像（MRI）的回顾性评估。在6例病例中，知晓MRI结果的外科医生发现了MRI未显示的瘘管，而在1例患者中，MRI显示了手术中未发现的瘘管。我们建议，在经验丰富的外科医生难以确定瘘管路径的情况下，应进行MRI检查。
