Comparison of direct and indirect methods for quantification of regurgitation. Scatterplots of MR (black) and TR (red) demonstrate high agreement between direct and indirect methods of quantifying regurgitant flow volume (top panels) and regurgitant fraction (bottom panels) with both 4D flow (left panels) and 2D-PC (right panels) MRI. The solid line is the line of best fit using least squares method. The dashed lines indicate the asymptotic 95% confidence intervals (CI). r = Pearson correlation coefficient.
