摘　　要：目的:利用三维超声Xplane成像模式测量新生儿胼胝体、透明隔腔及小脑延髓池,并和二维超声测量方法进行对比,探讨其优势。方法:经前囟门扫查,分别采用普通二维超声及三维超声Xplane成像模式测量新生儿胼胝体及透明隔腔。经颞窗扫查,采用三维超声Xplane成像模式测量新生儿小脑延髓池的大小。结果:1部分足月新生儿出生后透明隔腔即消失,早产儿均存在,且早产儿透明隔腔体积大于足月新生儿;2普通二维超声测量方法及三维超声Xplane成像模式测量胼胝体不同部位前后径及左右径的参考值无明显差异,但采用三维超声Xplane成像模式明显节约时间;3新生儿小脑延髓池前后径与其体积之间无相关性。结论:采用三维超声Xplane成像模式测量新生儿胼胝体、透明隔腔及小脑延髓池的大小方便、快捷。Objective： To discuss the advantage of the three-dimensional ultrasound with Xplane imaging in measuring corpus callosum, cavity of septum pellucidum and cerebellomedullary cistern of the newborns. Methods： Scanning through the fontanelle window, ordinary two-dimensional ultrasound and three-dimensional ultrasound with xplane imaging were used to measure the size of the neonatal corpus callosum and the septum pellucidum cavity. Scanning through the temporal window, three-dimensional ultrasound with Xplane imaging was used to measure the size of the cerebellomedullary cistern. Results： ① Some cavity of septum pellucidum disappeared in full-term babies but all existed in premature babies, and the volume of cavity of septum pellucidum in premature babies was greater than that of full-term babies. ②There was no difference in the reference value of the corpus callosum beween the common two-dimensional ultrasound and the three-dimensional ultrasound with Xplane imaging, but three-dimensional ultrasound with xplane imaging obviously saved time. ③The anteroposterior diameter of the newborn cerebellomedullary cistern had no correlation with the volume. Conclusion： Three-dimensional ultrasound with Xplane imaging is convenient, fast and accurate in measuring the size of the corpus callosum, cavity of septum pellucidum and cerebellomedullary cistern.
