Access to valid vascular territory atlases is important to advance our knowledge regarding the pathophysiology of cerebrovascular diseases and the effects of interventions and treatments. To date, however, only crude cerebral vascular territory atlases exist based on digitization of colorized figures. Moreover, anatomical variations of the cerebral arteries and knowledge of this variation is essential to avoid misdiagnosis and to plan tailored treatment. Probabilistic vascular territory atlases are well suited to take this vascular variation into account and we demonstrate experiment-based vascular territory atlases of major arteries using arterial spin labeling based vascular territory mapping.
