Vascular space occupancy (VASO) fMRI may provide more quantifiable and localized hemodynamic measures of brain activitythan conventional BOLD measurements. Due to application of inversion recovery pulse, conventional approach for VASO measurements suffers from low imaging efficiency, high SAR and interference of inflow and CBF effect. We demonstrated that DANTE prepared single echo or multi-echo EPI can be used to acquire robust full brain multi-slice VASO activation with benefit of high image efficiency, low SAR without complication of inflow and CBF effect.
