Imaging of anorectal region has drastically changed during the last decade. Transrectal ultrasound and transrectal MRI can be used for staging the rectal tumours. Endoanal sonography can be applied for the classification of perianal fistulae and identification of anal sphincter defects in patients with faecal incontinence. Due to the limitations of endoanal sonography, endoanal MRI was introduced to assess the pathology related to the anal sphincter complex. Endoanal MRI seems superior to endoanal sonography. This paper describes the new developments of the imaging techniques and presents new insights in anatomy and pathology of the anorectum.
在过去十年间，肛肠区域的成像技术发生了巨大变化。经直肠超声和经直肠磁共振成像可用于直肠肿瘤的分期。肛管内超声可用于肛周瘘管的分类以及大便失禁患者肛门括约肌缺陷的识别。由于肛管内超声存在局限性，因此引入了肛管内磁共振成像来评估与肛门括约肌复合体相关的病理情况。肛管内磁共振成像似乎优于肛管内超声。本文描述了成像技术的新进展，并呈现了关于肛管直肠解剖学和病理学的新见解。
