As an initial and exploratory study, this work showed that young secondary hypertensive patients have lower WSSmax and WSSmean at the anatomical location of ICA-C3. This indicates that hypertension and anatomical location impacted hemodynamic. 
Fig.1. Nine planes were placed in different locations of the intracranial arteries (a). Velocity was defined as the maximum velocity of all voxels. The 20 time points represent different times of cardiac cycles (b).
