超声测量胎儿颈项透明层厚度在产前筛查中的应用

摘要

Ultrasonography oi the fetus is accurate and safe in diagnosis with non-invasive, no teratogenir efferts,and no additive effert. It's ruiTently the preferred diagnostic imaging method oi screening the ietal malformations and obstetrie prenatal diagnosis. Antenatal examination is the necessary method oi diagnosing ietal malformation currently, and at the 11-13+6weeks oi gestation ultrasound screening for the measurement oi ietal nuchal translucency is the most significant examination in first trimester oi pregnancy, which is especially now considered the most sensitive target ior screening the ietal chromosomal all normalities. Here is to make a review on the application oi ultrsonography measuring the thickness oi the ietal nuchal translucency in antenatal examination.%超声检查对胎儿无创伤、无致畸作用、无叠加效应,诊断准确且安全性高,是目前产科产前诊断与筛查胎儿畸形首选的影像诊断方法.产前筛查是目前诊断胎儿畸形的必要手段,孕11 ～13+6周超声测量胎儿颈项透明层(NT)厚度是孕早期诊断胎儿畸形最有意义的一项检查,特别是筛查染色体异常的较敏感的指标.现将超声测量胎儿NT厚度在产前筛查中的应用予以综述.
