摘　　要：目的探讨动态四维超声时间-空间相关成像(STIC)技术在胎儿心脏畸形筛查中的评估效能。方法择取2018年4月至2021年3月经本院收治的疑似胎儿心脏畸形的70例单胎高危孕妇病历资料作回顾性分析,产前均进行二维超声常规筛查及动态四维超声STIC技术筛查,以分娩随访及引产结局为"金标准",比较两种筛查方式心脏标准切面显示结果、心脏畸形筛查评估效能及漏诊、误诊具体情况。结果70例疑似胎儿心脏畸形的单胎高危孕妇经分娩随访及引产结局中,心脏畸形18例(25.71%),非心脏畸形52例(74.29%);除四腔心切面、主动脉弓切面、左室流出道切面、右室流出道切面及大动脉短轴切面外,动态四维STIC中三血管-气管切面、导管弓切面、上下腔切面显示率高于二维超声(P<0.05);经二维超声检查,灵敏度、特异度及准确率依次为77.78%、96.15%及91.43%,经动态四维超声STIC检查,灵敏度、特异度及准确率分别为88.89%、98.07%及94.29%;经二维超声及动态四维超声STIC检查,孕周处于晚期更易漏诊、误诊。结论二维超声及动态四维超声STIC检查均可用于胎儿心脏畸形筛查,而动态四维超声STIC检查为二维超声基础检查有益补充。此外,提倡于孕中期进行胎儿心脏畸形筛查,可降低漏诊、误诊情况。Objective To explore the evaluation performance of dynamic four-dimensional ultrasound time-space correlation imaging(STIC)technology in the screening of fetal heart malformations.Methods The medical records of 70 high-risk singleton pregnant women with suspected fetal heart malformations who were admitted to our hospital from April 2018 to March 2021 were selected for retrospective analysis.Routine twodimensional ultrasound screening and dynamic four-dimensional ultrasound STIC technology were performed before delivery.For screening,follow-up childbirth and the outcome of induction of labor are the“gold standards”,and compare the results of the standard view of the heart in the two screening methods,the evaluation efficiency of the heart deformity screening,and the specific circumstances of missed diagnosis and misdiagnosis.Results Seventy high-risk singleton pregnant women with suspected fetal heart malformations were followed up after delivery and the outcome of labor induction.There were 18 heart malformations(25.71%)and 52 non-cardiac malformations(74.29%);Except for the fourchamber view,the aortic arch view,and the left ventricle The outflow tract,right ventricular outflow tract,and short-axis view of the aorta,the three-vessel-tracheal section,catheter arch section,upper and lower cavity section of the dynamic four-dimensional STIC showed higher display rates than two-dimensional ultrasound(P<0.05);By two-dimensional ultrasound In the inspection,the sensitivity,specificity,and accuracy were 77.78%,96.15%,and 91.43% in sequence.After dynamic four-dimensional ultrasound STIC inspection,the sensitivity,specificity and accuracy were 88.89%,98.07%,and 94.29%,respectively;After two-dimensional ultrasound and Dynamic four-dimensional ultrasound STIC examination,the third gestational week is more likely to be missed and misdiagnosed.Conclusion Both two-dimensional ultrasound and dynamic fourdimensional ultrasound STIC examination can be used to screen for fetal heart malformations,while dynamic four-dimensiona
