A sample of two patients to explain the correlation between Tortuosity and Mean Arterial Pressure (MAP). Patient 1 shows a decrease in tortuosity index from t0 to t1 corresponding to a decrease in MAP value for this patient. Patient 2 shows a slight increase from t0 to t1 corresponding to an increase in MAP value for this patient. Hence, these results show that MAP is directly correlated to tortuosity of cerebral blood vessels.
