Despite potential advantages of performing ASL at 7T,
its successful implementation poses significant
technical challenges related to SAR constraints and
B1-inhomogeneities. In this work, we propose a
combination of FAIR QUIPSSII labelling scheme, utilizing
optimized tr-FOCI inversion pulses, and simultaneous
multi-slice, multi-echo EPI readout for high-SNR
whole-brain perfusion measurements. This approach offers
high temporal resolution simultaneous CBF and BOLD
measurements that can find application in both
neuroscientific and clinical studies at 7T.
