Value Of Fetal Intelligent Navigation Echocardiography With Color Flow Imaging(5D Heart Color) In The Display Of Key Diagnostic Elements In Basic Fetal Echocardiographic Views

Objective:To evaluate the value of fetal intelligent navigation echocardiography with color flow imaging(5D Heart Color)in the display of key diagnostic elements in basic fetal echocardiographic views.Methods:The 384 samples of heart volume that were included in this study from 220 fetuses.Pearson correlations were used to compare the detection rate of blood flow element between 5D Heart Color software and color Doppler flow imaging(CDFI)in basic fetal echocardiographic views,and the detection rate of blood flow between normal fetuses(control group)and fetuses with cardiovascular abnormalities(case group).Bland-Altman analysis was used to prove consistency and reliability of the results.Results:The 384 samples of heart volume that were included in this study(from 220 fetuses),finally,317 heart volumes(from 200 fetuses)were effectively acquired,and approximately 82.6%were successful.5D Heart Color software and CDFI showed a close correlation in displaying key cardiovascular blood flow information in key fetal echocardiographic diagnosis sections(r=0.88,P<0.05);The detection rates of blood flow elements in control group and case group were 87.3%and 91.9%,respectively,with an average of 89.6%(r=0.90,P<0.05).Bland-Altman analysis showed close consistency between inter-and intra-observations in the detection rates of blood flow elements,with the 95%confidence interval were(-0.1/+0.09)and(-0.09/+0.1),respectively,and the points outside the 95%credibility interval were 5.4%(17/231)and 5.7%(18/231),respectively.Conclusions:5D Heart Color software shows similar usefulness in the displaying key blood flow elements,comparing with CDFI,demonstrating higher reliability and repeatability in displaying fetal echocardiographic diagnosis views and diagnostic flow elements.
