Perfusion territory maps provide unique information for the characterisation of cerebral haemodynamics. Ultra-high field (7T) provides increased image SNR and perfusion sensitivity. Territorial Arterial Spin Labelling (TASL) performance relies on good coil coverage and B1 homogeneity, both issues at 7T. PICORE (Proximal Inversion with a Control for Off-Resonance Effects) based TASL with a FOCI pulse is implemented to address these limitations. We assess sharpness and efficiency of the inversion profile of the FOCI pulse. Selective inversion slabs are positioned to perform Territorial Arterial Spin Labelling of the LICA, RICA and BA at 7T, providing maps of the three vascular territories.
