ATT based flow territories
Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
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
2 = middle ACA
3 = distal ACA
4 = proximal MCA
5 = middle MCA
6 = distal MCA
7 = proximal PCA
8 = middle PCA
9 = distal PCA
