A hybrid method combing the advantage of Vascular Space Occupancy, Dynamic Susceptibility Contrast imaging, and susceptibility induced R2 increase by long half-life contrast agent MION are proposed to measuring absolute cerebral blood volume (CBV) with multiple slices on animal model. The correlation between these method are high and therefore a regression can be utilized to convert multi-slices relative CBV values to absolute quantifications, which could be beneficial to measuring whole brain perfusion on animal experiments.
