摘要
目的:探讨时间空间相关成像技术联合断层超声显像技术(TUI-STIC技术)在产前筛查常见心脏位置异常中的临床应用价值。方法:应用时间空间相关成像技术采集胎儿心脏的容积图像,再应用断层超声显像技术进行分析,要求清晰显示上腹部横切面及四腔心切面并标明左右方位。结果:199例心脏位置异常胎儿心脏容积数据经断层超声显像技术处理均获得满意的上腹部横切面及四腔心切面。其中右位心67例;左旋心5例;中位心7例;异位心2例;心脏移位107例;心脏异构11例。结论:判断胎儿心脏位置的主要切面是上腹部横切面和四腔心切面。时间空间相关成像技术联合断层超声显像技术简易、准确,可作为产前筛查胎儿心脏位置异常的有效方法。
Objective：To explore the clinical application value of spatiotemporal image correlation combined with tomographic ultrasound imaging（STIC-TUI technique） in prenatal screening of common cardiac malposition. Methods：STIC technique was used to collect fetal cardiac volume images,then TUI technique was used for analysis,the transverse section through the upper abdominal portion and four-chamber view were displayed clearly,and the positions were indicated. Results：Satisfactory transverse section through the upper abdominal portion and four-chamber view were obtained after analyzing the data of fetal cardiac volume of 199 cases with fetal cardiac malposition by TUI technique.Sixty-seven cases with dextrocardia,five cases with levoverted heart,seven cases with mesocardia,two cases with exocardia,one hundred and seven cases with displacement of heart,and eleven cases with heterogeneous heart were found. Conclusion：The main views to judge fetal cardiac position include transverse section through the upper abdominal portion and four-chamber view,STIC-TUI technique is simple and accurate,which can be used as an effective method for prenatal screening of fetal cardiac malposition.
