The last 2 decades have seen considerable advances in obstetric ultrasonography, which now forms part of routine prenatal care in most countries. Congenital anomalies often occur sporadically and unpredictably. The prenatal identification of an abnormal fetus allows the opportunity for prenatal counseling with a multidisciplinary team of experts, and a thorough discussion of pregnancy options. Furthermore, prenatal diagnosis can influence antepartum and intrapartum management, and permit the planning of the mode and site of delivery, thus ensuring optimal care of the fetus and the newborn. Prenatal surgical therapy can also be offered to fetuses with simple anatomic defects that have predictably devastating developmental consequences. This review discusses controversies regarding the accuracy, limitations and the roles of ultrasound in pregnancy.
过去20年里，产科超声检查取得了长足进展，目前在大多数国家已成为常规产前检查的一部分。先天性异常往往是偶发且不可预测的。产前识别异常胎儿为多学科专家团队进行产前咨询以及深入讨论妊娠方案提供了机会。此外，产前诊断可影响产前和产时管理，并有助于规划分娩方式和地点，从而确保对胎儿和新生儿的最佳护理。对于患有简单解剖缺陷且可预测会产生严重发育后果的胎儿，也可提供产前手术治疗。本综述讨论了有关超声在妊娠中的准确性、局限性及作用的争议。
