We review our experience with Magnetic Resonance Imaging (MRI) in the evaluation of 6 patients showing anorectal malformation, and 4 more with persistent postoperative fecal incontinence. Preoperative sagittal, axial and coronal planes were studied with special consideration to the pelvic and vertebral structures. The excellent resolution of MRI allowed accurate identification of the pelvic musculature in all patients, including those with bizarre sacral abnormalities. MRI revealed structural anomalies not detected previously, such as teathering cord, intraspinal lipoma, presacral mass and renal malformation. In our institution, MRI has replaced the CT scan in the study of patients suffering of persistent fecal incontinence. In non operated on cases of anorectal malformations, MRI determines with extraordinary accuracy the location of the rectal atretic pouch, the actual pelvic muscular quality, and the detection of previously unsuspected associated anomalies.
我们回顾了磁共振成像（MRI）在评估6例肛门直肠畸形患者及另外4例术后持续性大便失禁患者中的应用经验。术前对矢状面、轴面和冠状面进行了研究，特别关注盆腔和脊柱结构。MRI的高分辨率使我们能够在所有患者中准确识别盆腔肌肉组织，包括那些伴有奇异骶骨异常的患者。MRI还揭示了先前未检测到的结构异常，如脊髓栓系、椎管内脂肪瘤、骶前肿物和肾脏畸形。在我们机构，MRI已取代CT扫描用于研究持续性大便失禁患者。在未经手术治疗的肛门直肠畸形病例中，MRI能极其准确地确定直肠闭锁袋的位置、实际盆腔肌肉质量，并检测出先前未被怀疑的相关异常。
