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. en Wake Forest University arterial stiffness MRI PC-MRI phase contrast imaging pulse wave velocity A Novel Method to Assess Pulse Wave Velocity using Single Velocity Encoding in Phase Contrast Imaging Thesis Hamilton, Craig A Santago, Peter Smith, Thomas L Biomedical Engineering 2012-01-14 open.access
