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.
