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。
Abstract
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: ①Some 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.
