摘要:

三维超声可以立体方式显示胎儿解剖结构的形态、大小、空间关系及其活动情况。随着超声影像技术和计算机的发展,它在胎儿产前诊断中的应用日趋广泛,为传统二维产前胎儿复杂畸形的超声诊断提供了新手段,如胎儿心血管系统、神经系统、颜面部及骨骼系统畸形,减少了产科检查时间,降低了对检查者技能的依赖性,提高了诊断的精确性,具有重要的临床意义。

Abstract:

Abstract:Three-dimensional ultrasound can demonstrate the morphology,size,spatial relationships of fetal anatomic structures and fetal movement status in detail.Recent advances in the technology of ultrasound imaging allow almost all the organ system of fetal examinations by three-dimensional ultrasound. It provides a novel means for assessing fetal complicated defects in congenital heart disease ,central nervous system anomalies,facial and skeletal malformations by conventional two-dimensional ultrasound.It decreases the examination time ,reduces the dependence on individual skills and inproves diagnostic accuracy ,so makes a significant value in prenatal diagnosis.

Key words: three-dimensional, ultrasound ;fetal, prenatal diagnosis
