We incorporate a multiband acquisition with DABS ASL to
form a MB-DABS sequence to allow simultaneous assessment
of ASL and BOLD functional connectivity measures across
the whole brain. The use of MB-DABS improves the
temporal SNR of both ASL and BOLD data. Using single
band DABS ASL, only the visual network can be reliably
detected using ASL, whereas with dual slice multiband
acquisition ASL, multiple networks are identified, in
line with the BOLD measures.
