Intracranial pulsatility index

1. Systolic blood pressure is associated with intracranial pulsatility index in humans (r=0.63).

   “Systolic BP was positively associated with cerebral PI in the MCAs in the VAH group only (r=0.63, p <0.01)”

1. Vertebral artery hypoplasia is associated with intracranial pulsatility index in humans.

   “However, the VAH group had greater ACAs PI ( p <0.01) compared with the noVAH group.”
