摘　　要：目的评价电子矩阵时间-空间相关成像(eSTIC)技术显示胎儿心脏诊断切面是否较时间-空间相关成像(STIC)技术具有优势。方法2019年1月至6月在绍兴市妇女儿童医院超声科进行产前超声检查的孕妇中,随机选择四腔心观上脊柱在5点至7点的18~24周正常胎儿64例。分别应用电子矩阵容积探头、传统机械容积探头采集同一胎儿心脏容积数据,存盘并脱机分析。应用正交三平面模式、断层超声显像模式显示胎儿心脏8个诊断切面:标准四腔心观、左心室流出道观、右心室流出道观、三血管-气管观、腹部横切观、动脉导管弓长轴观、主动脉弓长轴观、上下腔静脉-右心房观。将各个切面观重建图像的质量分为优、一般、差三级,质量为优、一般定义为合格,质量差定义为不合格。应用配对χ2检验对比2种方法显示心脏各诊断切面的合格率,应用配对秩和检验对比2种方法获得的心脏各诊断切面的成像质量的差异。结果2种技术均采集容积数据64个,采集成功率均为100%。eSTIC、STIC对于标准四腔心观、左心室流出道观、右心室流出道观、三血管-气管观、腹部横切观的显示合格率差异均无统计学意义(P均>0.05),但对于动脉导管弓长轴观、主动脉弓长轴观、上下腔静脉-右心房观,eSTIC显示合格率均优于STIC(均为93.8%vs 71.9%),差异均具有统计学意义(χ2均=11.925,P均=0.001)。eSTIC所有诊断切面重建图像的质量均优于STIC,差异有统计学意义(P均<0.05)。结论eSTIC能显著提高胎儿心脏诊断切面重建图像的成像质量。与STIC相比,eSTIC对胎儿心脏纵向诊断切面的显示更具优势。Objective To evaluate whether electronic spatial-temporal image correlation(eSTIC)technology has advantages over spatial-temporal image correlation(STIC)technology in displaying fetal heart diagnostic views.Methods This was a self-control trial of 64 normal singleton fetuses at 18 to 24 weeks of gestation who underwent prenatal ultrasound examination at the ultrasound department of Shaoxing Women&Children's Hospital from January to June 2019.In all fetuses,the position of the spine in the four chamber view was from 5∶00 to 7∶00.For each fetus,eSTIC and STIC of the fetal heart were performed with an electronic 4D probe and a conventional mechanical 4D probe.respectively.The sonographic volumes were computer stored and subsequently analyzed using 4D view software.Eight diagnostic views of fetal heart were displayed by orthogonal triplane mode or tomographic ultrasound imaging mode:(1)standard four chamber;(2)left ventricular outflow tract;(3)short-axis view of great vessels/right ventricular outflow tract;(4)three vessels and trachea;(5)abdomen/stomach;(6)ductal arch;(7)aortic arch;and(8)superior and inferior vena cava.The quality of the reconstructed images was categorized into three levels:excellent,fair,and poor.Excellent or fair quality was regarded as qualified,and poor quality was regarded as unqualified.Paired Chi square test was used to compare the qualified rate of the two methods,and the image quality of the two methods was compared by rank sum test.Results Both technologies collected 64 volume data sets,and the acquisition success rates were both 100%.There were no significant differences in the qualified rates of eSTIC and STIC for standard four chamber view,left ventricular outflow tract view,short-axis view of great vessels/right ventricular outflow tract,three vessels and trachea view,and abdomen/stomach view(P>0.05),but for ductal arch view,aortic arch view,and superior and inferior vena cava view,the qualified rates of eSTIC were better than those of STIC(93.8%vs 71.9%for all),and the differenc
