(a) and (b) Bar graph (upper) shows the average peak systolic velocities for each volunteer measured from PC-MR and from CFD. Velocities are consistently greater with PC-MR than with CFD. Scatter plot (lower) shows the correlation of velocity measurements with CFD and PC-MR in participants. The correlation appears roughly linear. The coefficient of determination is 0.7 and the goodness of fit is 0.6. PC: phase-contrast; MR: magnetic resonance; CFD: computational fluid dynamics.
