A new 3D arterial spin labeling (ASL) acquisition using multi-slab 3D gradient and spin echo (GRASE) was proposed, which shortened scanning time without sacrificing measurement accuracy. We have shown that the ASL imaging based on a multi-slab 3D GRASE sequence provided equivalent results in the absolute quantification of the CBF to that of the single slab sequence. The feasibility of this new multi-slab 3D acquisition approach was demonstrated by its better time efficiency and equivalent quantification accuracy.
