ATT based flow territories

These flow territories were created based on the Tatu et al. Neurology 1998 vascular territories, using arterial transit time (ATT) data from a population of elderly with hypertension. They correspond to Figure 2 of Plos One paper "Cerebral perfusion measurements in elderly with hypertension using arterial spin labeling". Data is stored in a regular nifti-file, without compression. Regions are encoded as follows: 1 = proximal ACA<br>2 = middle ACA<br>3 = distal ACA<br>4 = proximal MCA<br>5 = middle MCA<br>6 = distal MCA<br>7 = proximal PCA<br>8 = middle PCA<br>9 = distal PCA
