abstract

The measurement of pulse wave velocity (PWV) using conventional phase contrast magnetic resonance imaging (PC-MRI) is recognized as a standard technique to assess arterial stiffness by measuring the arrival times of blood velocity waveforms. Conventional PC-MRI requires the acquisition of two sets of complex images with different velocity sensitivities or encodings. The two sets of phase images are then subtracted to yield a final quantitative velocity image independent of background phases, i.e. non flow related phase variations stemming from the magnetic field inhomogeneities. However, the acquisition of two sets of images represents a significant increase in scan time (or reduce in temporal resolution), thus limiting its application for PWV assessment.
