摘要
目的探讨二维超声心动图联合时间-空间关联成像(STIC)技术在胎儿先天性心脏病(CHD)筛查中的应用价值。方法采用多切面顺序扫查法对11 036例胎儿进行心脏检查,部分胎儿进行STIC技术容积数据库采集及脱机分析,CHD胎儿引产后进行尸体解剖或出生后随访结果对照。结果单纯二维超声心动图筛查出176例胎儿先天性心脏大血管结构异常(不包括心律失常),其中97例在二维超声基础上进行STIC技术检查,92例两种方法检查结果一致(其中1例合并心内畸形漏诊);检出的CHD胎儿中,87例记录二维筛查时间,平均每个胎儿心脏用时(9.68±2.13)min,79例记录STIC技术扫描时间,平均每次STIC扫描用时(7.76±2.42)min;不同孕周二维超声心动图与STIC技术各重要切面显示合格率差异无统计学意义。结论 STIC技术可作为二维超声心动图的有效补充手段,二者联合可进一步提高胎儿CHD的产前诊断率。
Objective To explore the application value of two-dimensional echocardiography with spatio-temporal image correlation （STIC） in fetal congenital heart disease （CHD） prenatal ultrasonography. Methods 11 036 hearts of fetus were inspected by severalviews order scanning method and for STIC volume database acquisition and off-line analysis congenital heart disease fetus for autopsy after induced labor or contrast the follow-up results after birth. Resuits 97 cases with spatio-temp-oral image correlation in 176 cases congenital heart and great vessels exception （dysrhythmias not including） with simple two-dimensional echocardiography,92 cases were accordant （one case with incorporative intraeardiac malformation missed diagnosis）;in screened congenital heart disease fetus, STIC （n =79） and routine ultrasonography （ n = 87） took （7. 76 ± 2. 42） rain and （9. 68 ± 2. 13 ） rain per case, respectively; in different gestational weeks,the quality of the images derived from volume datasets were comparable to that directly obtained from 2D echocardiography. Conclusion STIC technology can be used as effective supplementary means of 2D echocardiography, and the combination can further improve the prenatal diagnosis of fetal congenital heart disease.
