To achieve comprehensive insight into g-factor, leakage
contamination and non-sequential slice acquisition order
effects of MB EPI on ASL perfusion imaging, both imaging
studies and theoretical evaluations were performed,
indicating that even in the presence of inter-slice
signal leakeage, MB EPI greatly benefits high-resolution
whole brain ASL perfusion imaging with respect to both
SNR efficiency and CBF quantification.
