摘　　要：目的 探讨孕20～40周正常胎儿胼胝体发育规律.方法 应用超声对340例清晰显示胼胝体的孕20～40周正常胎儿进行胼胝体长径、横径、厚径的测量,并将其各径线与孕周进行直线相关分析比较.结果 正常胎儿胼胝体各径线与孕周（GA）呈正相关,长径=3.605＋1.269 （GA） （r=0.961,P＜0.01）,宽径=1.257＋0.177 （GA） （r=0.987,P＜0.01）,厚径=0.532＋0.053 （GA） （r=0.952,P＜0.01）.结论 正常胎儿胼胝体的发育与孕周呈正相关,不同孕周各径线的参考值为产前超声诊断胼胝体发育不全提供直接诊断依据,可用于胎儿孕周的确定,并评价胎儿宫内发育迟缓情况.Objective To explore the development of corpus callosum in normal fetuses of 20 to 40 weeks gestation. Methods Three hundred and forty fetuses of 20 to 40 weeks gestation clearly showing corpus caltosum were measured by ultrasound for long diameter, wide diameter, thick diameter. Correlation between of gestational age and various diameters were analyzed. Results The development of corpus callosum in normal fetuses was positively correlated with gestational age, long diameter=-3.605＋ 1.269 （GA） （r=0.961, P〈0.01）, wide diameter=l.257＋0.177 （GA） （r=0.987, P〈0.01）, thick diameter=0.532＋0.053 （GA） （r=0.952, P〈0.01）. Conclusion The development of cor- pus callosum in normal fetuses is positively correlated with gestational age, Different diameters of the gestational age can provide direct diagnostic evidence for prenatal ultrasound in the diagnosis of agenesis of corpus callosum, which also can be used to determine the gestational age of the fetus and to evaluate fetal palace situation within retardation.
