In this study, we combined high-field (7 T) VASO with a
simultaneous-multi-slice (SMS) acquisition scheme. We
implemented and evaluated this method for simultaneous
acquisition of functional changes in cerebral blood
volume and BOLD signal at high spatial resolution, using
a visuo-motor task, and covering a large number of brain
areas including V1, V5, M1, and S1. We show that
SMS-VASO can measure blood volume changes with high
spatial resolution and satisfactory CNR, across multiple
brain regions and with better local specificity than
GE-BOLD signal.
