Figure 1 Velocity-Encoded Phase Contrast Magnetic Resonance Imaging in Aortic Stenosis
Sampling planes in the left ventricular outflow tract and after the aortic valve allow measurement of quantitative flow by velocity time integration (gray area under the curve). Functional aortic valve area is then calculated by continuity equation. Adapted, with permission, from Caruthers et al. (62).
