超声检查是产科首选的影像学方法.在11～13+6孕周超声测量胎儿颈项透明层(NT)厚度对降低围产儿出生缺陷率,尤其在胎儿染色体异常和结构异常上发挥重要作用.随着产前筛查、产前诊断技术的不断提高,对胎儿颈项透明层的研究也越来越深入.本文综合近些年国内外文献,就超声测量胎儿颈项透明层在产前筛查、产前诊断中的应用展开综述.“,”Ultrasonography has the advantages of safe,un-invasive,fast and reliable and practical.It is the first choice of imaging methods for obstetrics.In 11 ～ 13 + 6 weeks,ultrasonic measurement of fetal nuchal translucency (NT) thickness plays an important role in reducing perinatal birth defects,particularly in the fetal chromosomal abnormalities and structural abnormalities.With the continuous improvement of prenatal screening and prenatal diagnosis technology,the study on fetal NT thickness is becoming more and more deeply.Comprehensive domestic and foreign literature in recent years,the application of ultrasound in prenatal screening and prenatal diagnosis are reviewed in this paper.
