Key result
Radially undersampled 4D PC-MRI provided reliable pulse wave velocity measurements (3.8-4.8 m/s) comparable to 2D PC-MRI (4.6-5.3 m/s), with TTU, TTF, and XCorr as the preferred algorithms.

Supports 4D PC-MRI feasibility for PWV in volunteers; leaves open patient validation and outcome studies.
Wentland et al. (2012) conducted a cross-sectional in Healthy volunteers (n=18). Radially undersampled 4D phase-contrast magnetic resonance imaging (PC-MRI) vs. High temporal resolution 2D PC scans was evaluated on Pulse wave velocity (PWV) measurements and algorithm reliability. Radially undersampled 4D PC-MRI provided reliable pulse wave velocity measurements (3.8-4.8 m/s) comparable to 2D PC-MRI (4.6-5.3 m/s), with TTU, TTF, and XCorr as the preferred algorithms.
