Abstract: 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.
