【摘要】：【目的】探讨四维超声联合高分辨血流成像(HD flow)在观察胎儿肺静脉中的应用价值。【方法】本研究纳入2015年6月-2016年6月在我院接受产前胎儿心脏超声检查的胎儿130胎。于胎儿四腔心切面分别应用彩色多普勒和高分辨血流成像观察并计数肺静脉的显示数目。在开启HD flow状态下,于胎儿四腔心切面采集心脏三维容积数据,利用图像后处理软件对容积数据分析重建,获取胎儿肺静脉的三维图像,观察并计数肺静脉的显示数目。对比三种方法对正常125例胎儿肺静脉的显示情况。对于肺静脉回流异常的5例胎儿,采用STIC联合HD flow技术对肺静脉进行三维重建,观察肺静脉的异常回流途径。【结果】HD flow对胎儿肺静脉的显示率要高于彩色多普勒,对于17~32周的胎儿四维超声联合HD flow可以更好的观察肺静脉的空间位置关系。【结论】在孕周较小时,STIC联合HD flow技术可更好地显示胎儿肺静脉,且三维重建图像更直观、立体,有助于理解其空间关系。
[Abstract]:[objective] to evaluate the value of four dimensional ultrasound combined with high resolution flow imaging (HD) in observing fetal pulmonary veins. [methods] this study was included in prenatal fetal heart ultrasound examination in our hospital from June 2015 to June 2016. 130 fetuses. Color Doppler imaging and high resolution flow imaging were used to observe and count the number of pulmonary veins on the four-chamber central section of the fetus, respectively. When HD flow was turned on, The three-dimensional volume data of the fetal pulmonary vein were obtained by using the image post-processing software to analyze and reconstruct the three-dimensional volume data of the fetal pulmonary vein. The number of pulmonary veins was observed and counted. The display of pulmonary veins in 125 normal fetuses was compared by three methods. For 5 fetuses with abnormal pulmonary venous reflux, STIC combined with HD flow technique was used to reconstruct the pulmonary veins. [results] the display rate of fetal pulmonary vein by HD flow was higher than that by color Doppler. Four-dimensional ultrasound combined with HD flow at 1732 weeks could better observe the spatial position relationship of pulmonary veins. [conclusion] STIC combined with HD flow can better display fetal pulmonary veins at the early gestational age, and 3D reconstruction images are more visual and stereoscopic. Helps to understand its spatial relationship.
