We used timing parameters from a variety of
perfusion-based MR imaging techniques (ASL, DSC-, and
DCE-MRI) in order to investigate the major hemispheric,
subcortical, and cerebellar perfusion territories and
intervening watershed zones in a group of healthy
volunteers with non-variant circle of Willis anatomy. An
MNI space atlas was then constructed delineating a
probabilistic map of these perfusion territories, the
first time such a map has been produced from in vivo
data. Such information is invaluable to those
investigating links between neurovascular hemodynamics
and other neurological conditions.
