Background suppression (BS) can increase SNR of ASL
images by suppressing the background signal and raise
temporal SNR. Recently ASL with simultaneous multi-slice
(SMS) or multiband (MB) EPI has been successfully
implemented which shortens the total time of the EPI
readout trains, which can be used to reduce inversion
time variations in BS. In this work, background
suppression is implemented and evaluated in pseudo
continuous ASL (pCASL) SMS-EPI to increase the temporal
SNR and SNR.
