Supports MRI PWV measurement via waveform foot in reflected-wave models; leaves open in vivo applicability.
Can an MRI projective velocity encoding sequence accurately determine pulse-wave velocity in an artery model in the presence of reflected waves?
In vitro validation demonstrates that MRI projective velocity encoding can reliably measure pulse-wave velocity using the foot of the waveform, even when large reflected waves are present.
Stevanov et al. (2001) studied this question. Magnetic resonance imaging projective velocity encoding sequence vs. Theoretical model was evaluated on Pulse-wave velocity determined from the spatial and temporal separations of the foot of the velocity waveform. Magnetic resonance imaging projective velocity encoding sequence can determine pulse-wave velocity in the presence of reflected waves by using the foot of the waveform as a characteristic point.
