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.
