In 17 patients with anorectal fistulae the pelvis was examined by magnetic resonance imaging (MRI). The extent and the course of the fistulae and abscesses could be visualized by proton-density- and T2-weighted images. In 6 of 17 patients fistulae were seen that could not be detected by clinical investigation. In 2 cases additional pelvirectal abscesses were found. Most of the fistulae (5 of 6) had a complicated high suprasphincteric or rectovaginal course. It is concluded that with MRI anorectal fistulae and abscesses can be visualized and that this method is a worthful additional diagnostic tool in patients with complicated fistula-in-ano.
对17例肛门直肠瘘患者进行了骨盆磁共振成像（MRI）检查。通过质子密度加权像和T2加权像可显示瘘管及脓肿的范围和走行。17例患者中有6例发现了临床检查未能检测到的瘘管。2例发现了额外的盆腔直肠脓肿。大多数瘘管（6例中的5例）有复杂的高位括约肌上型或直肠阴道型走行。结论是，MRI可显示肛门直肠瘘和脓肿，该方法是复杂性肛瘘患者一种有价值的辅助诊断工具。
