Functional ASL has a higher specificity and
reproducibility than BOLD fMRI. However, the perfusion
related signal is typically in the range of a few
percent and the spatial and temporal resolution of
arterial spin labeling imaging rather limited. ASL at
ultra-high field can benefit from higher intrinsic SNR
and increased longitudinal relaxation times. We
investigated bSSFP and GRE-EPI as possible readout
schemes for fASL studies at 9.4 T and were able to
measure the first time stimulus evoked perfusion changes
in the human motor cortex at this field strength.
