Key result
Aortic flow wave velocity measured noninvasively by MRI increased linearly with age (r = 0.87) and was negatively correlated with ascending aortic compliance (r = -0.75).
Population
20 healthy volunteers of different ages (including decades 10-19 to 50-59)

MRI aortic flow wave velocity may support noninvasive stiffness assessment with aging; leaves open prognostic or therapeutic utility.
Cross-Sectional (n=20)
Effect estimate: r = 0.87
MRI with cine velocity mapping noninvasively demonstrates that aortic flow wave velocity increases linearly with age and correlates negatively with aortic compliance.
Mohiaddin et al. (1993) conducted a cross-sectional in Healthy volunteers (n=20). Magnetic resonance imaging with cine velocity mapping was evaluated on Flow wave velocity in the thoracic aorta (r = 0.87). Aortic flow wave velocity measured noninvasively by MRI increased linearly with age (r = 0.87) and was negatively correlated with ascending aortic compliance (r = -0.75).
