Figure 1

Regression and agreement of valve effective orifice area methods. Panel A shows the regression fit of the valve effective orifice area (EOA) measured by the continuity equation using 2D flow MRI (EOA-CE) and the 4D flow MRI EOA measured by the jet shear layer detection (JSLD) method (EOA-JSLD). Panel B shows the corresponding Bland-Altman agreement plot for both methods.
