摘　　要：目的探讨产前超声检测胎儿胼胝体发育及诊断胼胝体发育不全(ACC)的价值。方法应用彩色超声诊断仪测量621例孕20～40周正常单胎胎儿胼胝体长度、宽度及厚度,并与孕周(GA)进行相关回归分析比较。对15例产前超声诊断并经产后随访证实的ACC胎儿声像图特征进行回顾性总结和分析。结果胎儿胼胝体各径线与孕周呈正相关。结论超声产前检查诊断胎儿胼胝体发育不全具有较高的临床价值。Objective：To measure the corpus callosum（CC） in the developing fetuses and to diagnose the agenesis of corpus callosum（ACC）.Methods：A total of 621 consecutive fetuses between 20 and 40 gestational weeks were included in the prospective study.The length,width and thickness of the CC were measured with Color Doppler ultrasound.Piecewise regression analysis was used to study the relationships between the length,width and thickness of the fetal CC and gestational age（GA）.15 cases of fetuses with ACC who were postnatal confirmed were analyzed retrospectively.Results：Regression analysis revealed significant associations between the length,width,thickness of the fetal CC and GA.They are positively correlated.Conclusion：Prenatal sonographic offer normative data for fetal CC and a high clinal significance in the diagnosis of fetal ACC.
