Magnetic resonance defecography is an effective method of evaluating pelvic floor weakness and anorectal dysfunction. With no ionizing radiation, less than 30 minutes of imaging, and complete anatomic and functional detail, magnetic resonance has largely supplanted other imaging modalities. This contribution reviews the pertinent pelvic anatomy, image acquisition, and image interpretation and briefly discusses the most common pathology.
磁共振排粪造影是评估盆底功能障碍和肛门直肠功能障碍的有效方法。由于无电离辐射、成像时间少于30分钟且能提供完整的解剖和功能细节,磁共振成像在很大程度上已取代了其他成像方式。本文献综述了相关的盆腔解剖、图像采集和图像解读,并简要讨论了最常见的病理情况。
