Accurate prenatal diagnosis of fetal anomalies is essential for making decisions on pregnancy management options and for the determination of recurrence risk. However, the types of congenital anomalies that should be diagnosed using routine sonography are difficult to define. Factors that can affect the ultrasonographic detection of a particular congenital abnormality include equipment resolution, the time in gestation when the anomaly becomes apparent, and sonographer or sonolist experience. This review outlines the work that has been done over the past year to improve the detection rate of specific second trimester congenital malformations.
准确的胎儿异常产前诊断对于做出妊娠管理方案的决策以及确定复发风险至关重要。然而，使用常规超声检查应诊断出的先天性异常类型难以界定。可能影响特定先天性异常超声检测的因素包括设备分辨率、异常变得明显时的妊娠时间以及超声检查人员或超声诊断师的经验。本综述概述了过去一年为提高孕中期特定先天性畸形的检出率所开展的工作。
