In this study, a pCASL and two PASL variants at 3 T are
compared with a PASL approach at 7 T to determine, which
of the techniques is most suited for simultaneous high
temporal resolution functional CBF and BOLD
measurements. The 3 T techniques show no significant
differences in either grey matter perfusion or temporal
SNR values. In contrast, the 7 T variant tested delivers
significantly lower grey matter CBF and temporal SNR
values, while offering improved BOLD sensitivity. This
indicates that further technical improvements might be
necessary for 7 T ASL to be able to reach its full
potential.
