摘　　要：目的：探讨三维超声成像技术在胎儿胼胝体结构清晰显示方面的优势和价值。方法：选取54例接受产前超声检查的正常孕妇,分别利用二维及三维超声技术观测胎儿胼胝体,并测量不同孕周胼胝体前后径。结果：54例孕妇中,通过二维超声成功显示并测量胼胝体结构的有18例,三维超声成像成功测量所有胎儿胼胝体结构,三维超声胼胝体的显示率明显高于二维超声（100.0%vs 33.3%,χ~2=54.0,P〈0.001）,三维超声与二维超声测量数据高度相关（r=0.948,P〈0.001）。结论：三维超声对胎儿胼胝体的显示明显优于二维超声,同时对胎儿胼胝体生长发育的监测有重要价值。Objective To study on the advantage and value of three-dimensional ultrasound imaging in the display of fetal corpus callosum. Methods Total, of 54 normal pregnant women received prenatal ultrasound examination were selected to observe fetal corpus callosum by using two- and three-dimensional ultrasound, and to measure the anteroposterior diameter of the corpus callosum in different gestational weeks. Results Among 54 eases of pregnant women, the structure of the corpus callosum were successfully displayed and measured by using two-dimensional ultrasound in 18 cases, and all fetal corpus callosurn were successfully measured by using three-dimensional ultrasound. The display rate of corpus callosum of three- dimensional ultrasound was significantly higher than that of two-dimensional ultrasound （100.0% vs 33.3%, x2=54.0, P〈 0.001）, and measurements of the three-dimensional ultrasound were highly correlated to those of two-dimensional ultrasound （r=0.948, P〈0.001）. Conclusion Three-dimensional ultrasound is superior to two-dimensional ultrasound in the display of fetal corpus callosum, showing significant value in monitoring the growth and development of fetal corpus callosum.
