【摘要】 目的　探讨胎儿脸面部三维超声成像的方法及其临床应用。方法　采用表面成像方法对 92例中晚期妊娠胎儿的脸面部进行三维超声成像。结果　 92例孕妇中 ,90例均清楚显示胎儿脸面部的表面特征、立体形态及各结构间的位置关系 ,2例因前方羊水较少显示不满意。结论　胎儿脸面部的三维图像可提供更丰富的诊断信息 ,可作为二维超声诊断的补充 ,提高对胎儿脸面部畸形的产前诊断率。同时使孕妇及其他非超声工作人员更直观地观察胎儿面部结构 ,使准妈妈们提前与腹中宝宝见面。更多还原

【Abstract】 Purpose To discuss ultrasonic three-dimensional image construction of fetal face and its clinical application. Methods Superficial image construction method was used to construct three-dimensional ultrasonic image of fetal face during late pregnancy. Results Among 92 fetus, 90 were clearly shown their face character, solid shape and positional relationship between structures, other 2 fetuses failed to do so because of oligohydramnios. Conclusion Three-dimensional image of fetal face can provide more abundant diagnostic information, which not only make up the drawback of simple three-dimensional ultrasonic diagnosis, but also form a more correct prenatal diagnosis of fetal face anomaly. Simultaneously, it let the pregnant women and other people observe the face structure of fetus more directly, which could only be seen after childbirth by mothers before.更多还原
