Ultrasound screening of structural fetal malformations is mainly based on the use of ultrasounds during the second trimester of pregnancy. The diagnostic sensibility of ultrasounds varies in the different multicentric studies reported in literature and is correlated to different factors: gestation period, type of malformation, number of ultrasounds performed, operator experience, etc. Third trimester ultrasounds may identify late-onset malformations and offer adequate information for postnatal assistance.
胎儿结构畸形的超声筛查主要基于在妊娠中期使用超声。文献报道的不同多中心研究中，超声的诊断敏感性各不相同，且与不同因素相关：妊娠期、畸形类型、超声检查次数、操作者经验等。孕晚期超声可识别迟发性畸形，并为产后护理提供充分信息。
