The purpose of this study was to evaluate the hemodynamic changes in the cerebral arterial of healthy adults among different ages and anatomical locations by using 4D flow MRI. We measured blood flow volume, velocity, wall shear stress (WSS) of cerebral arterial. The hemodynamic changes among different groups were significantly distinct. The young group showed significantly higher in velocity and WSS. Velocity and WSS were decreased with age. The proximal posterior cerebral artery (pro-PCA) had lower volume, velocity and WSS than other parts. 4D Flow MRI could quantify the change of hemodynamics parameters in the cerebral arterial of healthy adults.
