Due to various challenges, there exist only few arterial
spin labeling imaging studies at 7T, and most mainly
focused on superior brain region. Recently, Multi-Band
(MB) imaging, as a novel method reducing MRI time with
increased spatial or temporal resolution, was applied at
3T using FAIR. Here, the feasibility of applying MB EPI
pCASL for whole brain perfusion imaging at 7T has been
explored and demonstrated with passive B1 and 3rd B0
shimming optimization, showing that up to 10 times
acceleration can be achieved for MB EPI in pCASL imaging
with acceptable data quality for assessing perfusion.
