Pulse wave velocity can be derived from sequential 2D phase contrast measurements in multiple breath-holds, resulting in a long scan time and patient discomfort. Physiological conditions, may change during the measurement series, leading to flow waveform shifts and hence errors in PWV estimation. We developed a prototype SMS cine-PC sequence to measure blood flow in multiple slices simultaneously and applied it to measure PWV in the aorta.
