目的 探讨如何提高产前胎儿心脏超声筛查的效率.方法 以心尖四腔心为起始切面,使用时空关联成像(spatio-temporal image correlation,STIC)技术采集83例正常胎儿心脏的容积数据,利用超声断层成像(tomographic ultrasound imaging,TUI)技术进行脱机分析,获取胎儿心脏筛查所需要的9个切面,并与二维(two-dimensional,2D)超声检查的图像进行质量及分析效率的比较.结果 83例均获取满意的图像.(1)TUI对大动脉短轴的合格率显著高于2D(94.0％与84.3％,x2 =5.57,P=0.042),对其他8个切面,TUI合格率高于2D,差异无统计学意义.(2)TUI对于四腔心、五腔心、左室流出道、右室流出道和大动脉短轴切面的显示和2D达到了极好的一致性(Kappa分别为0.79、0.90、0.92、0.93和0.77)；对于主动脉弓、动脉导管弓腔静脉长轴和心室短轴切面的显示和2D的一致性较好(Kappa分别为0.72、0.67、0.74和0.70).(3)STIC采集时间短于2D检查时间[(0.85±0.18) min与(5.80±1.58) min,t=3.500,P=0.000],STIC采集+TUI分析时间亦短于2D检查时间[(3.29±1.13) min与(5.80±1.58)min,t=2.877,P=0.001].结论 STIC联合TUI能方便、快捷、清晰地显示胎儿心脏筛查的9个切面,有助于提高胎儿心脏超声筛查工作的质量及效率.

Objective To explore how to elevate the efficiency of fetal heart screening.Methods Volume data of 83 normal fetuses ranging between 20 to 24 gestational weeks were acquired by spatiotemporal image correlation (STIC) with the apical four-chamber view(4CV).Tomographic ultrasound imaging (TUI) was then used to present the different views of fetal hearts,and were compared with those aquired by 2-dimensional (2D) ultrasound.Results All the 83 volume datasets were obtained by STIC.(1) Qualification ratio of short axis view of the aorta (SAV) by TUI was higher than that of 2D (94.0％ vs 84.3％,x2 =5.57,P=0.042).While,in the other 8 planes,the qualification ration by STIC were higher than that of 2D,however no significant difference was found (P＞0.05).(2) In 4CV,5-chamber view (5CV),left ventricular outflow tract view (LVOT),right ventricular outflow tract view (RVOT) and SAV,STIC showed excellent consistency with 2D (Kappa =0.79,0.90,0.92,0.93 and 0.77,respectively).And in long axis view of the aortic arch (LAV-AoA),long axis view of the duct (LAV-DA),superior and inferior vena cava (SVC+IVC) and short axis view of the ventricle (SVV),STIC showed good agreement with 2D (Kappa=0.72,0.67,0.74 and 0.70,respectively).(3) Image collecting time of T2D,TSTIC,TTUI and TSTIC+TUI were (5.80±1.58) min,(0.85±0.18) min,(2.57±1.32) min and (3.29±1.13) min,respectively.There were significant difference between TSTIC and T2D(t=3.500,P=0.000) and between TSTIC+TUI and TTUI (t=2.877,P=0.001).Conclusion The technique of STIC-TUI used in this study can display the standard planes of fetal heart conveniently,clearly and in shorter time.It is helpful for improving the quality and efficiency of fetal heart screening.
