Plannings-free selective arterial spin labeling MRI has the unique capacity to show the perfusion territories of brain feeding arteries non-invasively. The clinical applicability of this method is highly dependent on reliability and accuracy with which different flow territories can be identified. Therefore the aim of the present study was to determine whether RPI based flow territories are imaged sufficiently reliable and accurate to be used in a clinical setting.
