Determination of fetal left ventricular (LV) volume in two-dimensional echocardiography (2DE) is significantly important for quantitative analysis of fetal cardiac function.
A backpropagation (BP) neural network method is proposed to predict LV volume more accurately and effectively.
The 2DE LV border and volume are considered as the input and output of BP neural network correspondingly.
To unify and simplify the input of the BP neural network, 16 distances calculated from the border to its center with equal angle are used instead of the border.
Fifty cases (forty frames for each) were used for this study.
Half of them selected randomly are used for training, and the others are used for testing.
To illustrate the performance of BP neural network, area-length method, Simpson’s method, and multivariate nonlinear regression equation method were compared by comparisons with the volume references in concordance correlation coefficient (CCC), intraclass correlation coefficient (ICC), and Bland-Altman plots.
The ICC and CCC for BP neural network with the volume references were the highest.
For Bland-Altman plots, the BP neural network also shows the highest agreement and reliability with volume references.
With the accurate LV volume, LV function parameters (stroke volume (SV) and ejection fraction (EF)) are calculated accurately.
