PURPOSE
To document the imaging findings suggestive of anorectal malformation (ARMs) on prenatal US and MRI.
METHODS
Retrospective evaluation of the screening US and prenatal MRI exams of the rectum and ano-perineal region in normal fetuses and in patients with ARMs.
RESULTS
Examples showing the normal rectal and anoperineal anatomy on prenatal US and MRI exams and the imaging findings observed in different types of confirmed ARMS.
CONCLUSIONS
Prenatal diagnosis of ARMs requires both a systematic evaluation of the fetal pelvis and perineum and an appropriate knowledge of its suggestive imaging findings.
目的
记录产前超声（US）和磁共振成像（MRI）提示的肛门直肠畸形（ARM）的影像学表现。
方法
回顾性分析正常胎儿和 ARM 患者直肠和肛门会阴区域的筛查 US 和产前 MRI 检查结果。
结果
展示了产前 US 和 MRI 检查中正常直肠和肛门会阴解剖结构以及不同类型 ARM 观察到的影像学表现的示例。
结论
ARM 的产前诊断需要对胎儿骨盆和会阴进行系统评估，并对其提示性影像学表现有适当的了解。
