Key result
Ageing was independently associated with altered pulmonary hemodynamics, including reduced peak and average flow velocities and volumes, reflecting increased vessel stiffness.

Does age affect pulmonary artery blood flow measured by 4D flow CMR in the general population?
4D flow CMR demonstrates that aging independently alters pulmonary hemodynamics, reflecting increased vessel stiffness and reduced pulmonary circulation, providing a baseline for future pathological studies.
Wehrum et al. (2016) conducted a cross-sectional in Healthy general population (n=126). Ageing vs. Younger age groups was evaluated on Age-related changes in pulmonary artery blood flow parameters (e.g., mean flow, peak velocity, cross-sectional area). Ageing was independently associated with altered pulmonary hemodynamics, including reduced peak and average flow velocities and volumes, reflecting increased vessel stiffness.
