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).

patients and healthy adults.
