Figure 2

Experimental results. Panel A: Pixel-wise PIV repeatability for the highest pump setting. Panel B: PIV repeatability for peak velocities for all five pump settings. Panel C: Validation of 4D PC-MR velocities against PIV for the highest pump setting. Panel D: Validation of 4D PC-MR peak velocities against PIV for all five pump settings. 4D PC-MR underestimated peak velocities by 8-25% compared to PIV. All data taken at 400 ms from the initiation of flow.
