Abstract

OBJECTIVE

This study investigated the feasibility and accuracy of fetal intelligent navigation echocardiography (FINE) for the prenatal diagnosis of congenital heart disease (CHD) by inexperienced and experienced operators.

METHOD

In this prospective study, all volume data sets from 120 fetuses with a broad spectrum of CHD were acquired using spatiotemporal image correlation technology. The prenatal diagnostic procedures were performed by two operators with different experience (beginner: 1 year and expert: 15 years) using FINE and traditional fetal echocardiography. Data were analyzed on the time of examination and acquisition of results.

RESULTS

Diagnoses made by FINE and traditional echocardiography were completely consistent with the final diagnosis of CHD in 98 (81.66%) versus 20 (16.66%) (P < 0.001) beginners and 87.50% (n = 105) versus 101 (84.16%) experts, respectively. On the contrary, there was significant difference using traditional echocardiography (16.66% versus 84.16%, P < 0.001) by two examiners. Furthermore, the examination time decreased when using FINE compared with using traditional echocardiography (beginner operators: 4.54 ± 1.03 min versus 20.58 ± 3.36 min, P < 0.001; expert operators: 3.89 ± 0.96 min versus 12.73 ± 1.62 min, P < 0.001).

CONCLUSION

Based on our results, a prenatal diagnosis of CHD can be made with high feasibility and accuracy using FINE compared with traditional fetal echocardiography for beginner operators.

摘要

目的

本研究调查了经验不足和经验丰富的操作者使用胎儿智能导航超声心动图（FINE）对先天性心脏病（CHD）进行产前诊断的可行性和准确性。

方法

在这项前瞻性研究中，使用时空图像相关技术获取了120例患有广泛类型CHD胎儿的所有容积数据集。由两名经验不同的操作者（新手：1年经验，专家：15年经验）使用FINE和传统胎儿超声心动图进行产前诊断程序。对检查时间和结果获取时间进行了数据分析。

结果

FINE和传统超声心动图做出的诊断与CHD最终诊断完全一致的情况，新手分别为98例（81.66%）对20例（16.66%）（P<0.001），专家分别为87.50%（n=105）对101例（84.16%）。相反，两名检查者使用传统超声心动图时有显著差异（16.66%对84.16%，P<0.001）。此外，与使用传统超声心动图相比，使用FINE时检查时间缩短（新手操作者：4.54±1.03分钟对20.58±3.36分钟，P<0.001；专家操作者：3.89±0.96分钟对12.73±1.62分钟，P<0.001）。
