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.
