【摘要】 目的 探讨基于容积超声图像的心脏计算机辅助系统（SonoVCADS）在正常胎儿心脏诊断切面显示中的可行性。方法 选取2021年8月至2022年3月在丽水市中心医院超声科行胎儿心脏检查的66名正常单胎胎儿为研究对象，使用SonoVCADS获得容积超声图像314个。由3名不同经验的观察者对每个诊断切面进行评分，计算SonoVCADS显示诊断切面的成功率和一致性，比较3名观察者使用SonoVCADS显示胎儿心脏诊断切面的时间。另随机选取50名胎儿，比较SonoVCADS与二维超声心动图显示胎儿心脏诊断切面的时间。结果 3名观察者使用SonoVCADS显示胎儿心脏8个诊断切面的成功率比较，差异均无统计学意义（均P>0.05）。以观察者B（相对经验不足）为例，70.70%的容积超声图像可以成功显示8个诊断切面，13.69%的容积超声图像可以成功显示7个诊断切面，仅4.15%的容积超声图像成功显示的诊断切面数<4个。观察者B的8个诊断切面的Kappa值为0.652～0.854;3名观察者的8个诊断切面的Kappa值为0.536～0.752。观察者C（检查经验丰富）花费的时间明显少于观察者A和观察者B（均P<0.05）。观察者C使用SonoVCADS显示胎儿心脏8个诊断切面的时间明显短于二维超声心动图（P=0.018）。结论 SonoVCADS显示胎儿心脏8个诊断切面的成功率较高，对操作人员的依赖性低，且具有良好的一致性和检查效率。更多还原

【Abstract】 Objective To investigate the feasibility of sonography-based volume computer aided s ystem(Sono VC ADS) in displaying normal fetal hearts diagnostic sections.Methods Sixty-six normal singleton fetuses who underwent fetal cardiac examination at the department of ultrasound in Lishui Central Hospital from August 2021 to March 2022 were included.Three hundred and fourteen volume images were obtained using SonoVCADS.Each diagnostic section was scored by three observers with different experiences and the success rate and consistency of SonoVCADS in displaying eight diagnostic sections were calculated.The time consumed by the three observers in displaying fetal cardiac diagnostic sections using SonoVCADS was compared.Additionally,50 fetuses were randomly selected to compare the time in displaying diagnostic sections using SonoVCADS and two-dimensional echocardiography.Results The success rate in displaying eight diagnostic sections of fetal heart using SonoVCADS was not significantly different among the three observers(all P>0.05).Taking observer B(relatively inexperienced) as an example,70.70% of volume images successfully displayed 8 diagnostic sections,13.69% of volume images displayed 7 diagnostic sections,and only 4.15% of volume images displayed less than 4 diagnostic sections.The Kappa values for observer B in displaying eight diagnostic sections ranged from 0.652 to 0.854,which ranged from0.536 to 0.752 for the three observers.Observer C(more experienced) spent significantly less time than observers A and B(both P<0.05).The time in displaying eight diagnostic sections by observer C was significantly less using SonoVCADS than using two-dimensional ultrasound(P=0.018).Conclusion SonoVCADS exhibits a high success rate in displaying eight diagnostic sections of fetal heart,with low operator dependence,favorable consistency and diagnostic efficiency.更多还原
