Pulse Wave Velocity (PWV) MR imaging is an established technique to derive aortic stiffness. The underlying phase-contrast velocity data is typically acquired during multiple breath-holds within multiple 2D planes placed perpendicularly to the aorta. In this work we investigate the application of an auto-calibrated multiband approach to simultaneously excite and acquire three slices. With this technique all data is obtained in a single breath-hold and without the need of external reference scans. Blood velocities and PWV for different MB acquisitions are compared to results obtained with a singleband approach that excites each slice separately.
