In this work we describe scan twelve healthy human volunteers with phase contrast MRI. Cut planes were placed in twenty-six of the key cerebrovascular segments, and the surface integral of the flow velocity was calculated to yield the volume flow rate in ml per second. We found deviations in the volume flow rates on the order of 20-30% in larger vessels such as the carotid artery and found deviations on the order of 30-40% in smaller vessels such as the middle cerebral arteries.
