摘　　要：目的 探讨超声检查在产前诊断胎儿颅脑疾病中的应用价值.方法 对31例患胎儿颅脑疾病孕妇行二维超声、三维超声、磁共振检查,并与病理结果对照分析.结果 31例胎儿超声提示2例无脑儿,1例露脑,2例脑膨出,5例全前脑,2例蛛网膜囊肿,1例Galen静脉瘤,2例胼胝体发育不全,1例脑裂,3例Dandy-Walker畸形,7例侧脑室扩张,5例颅后窝池增宽,通过磁共振检查核对,三维超声诊断符合率100%,二维超声诊断符合率93.5%.结论 超声检查在胎儿颅脑疾病中有很高价值,三维超声比二维超声检查更直观.Objective To explore the application of three-dimensional （3D） ultrasonography in screening the defects of fetal brain and skull.Methods Thirty-one cases of the fetal were detected in 3D ultrasonography.The ultrasonic data were compared with magnetic resonance imaging（MRI） and pathology.Results Among 31 cases according to 3D ultrasonography,there were 2 of anencephaly, 1 of exencephaly,2 of encephalocele,5 of holoprosencephaly,2 of arachnoidcyst, 1 of vein of Galen aneurysm,2 of agenesis of the corpus callosum, 1 of schizencephaly, 3 of Dandy-Walker syndrome, 7 of ventriculomegaly, and 5 of enlargement of cisterna magna.Compared with the results of MRI,the diagnostic accordance rate was 100% by 3D,it was 93.5% by 2D.Conclusions The structure of fetal brain and skull were viewed more clearly in 3D ultrasonography than 2D ultrasonography and the defects of fetal brain and skull can screened more exactly.
