Age-related changes in 4D flow MRI derived peak/mean velocity, Wall Shear Stress (WSS), velocity Time To Peak (TTP) and Mid-Ascending Aortic diameter (MAA) were investigated in 60 healthy volunteers (19-79 years old). A significant increase in peak velocity (R=0.39,P=0.001), decrease in mean velocity (R=0.53, P<0.001), WSS (R=0.59, P<0.001), TTP (R=0.39, P=0.001) and MAA (R=0.57, P=<0.001) was found with increasing age. The results show the importance of matching patient age to the appropriate control group.
