Intracranial arterial calcification evaluation has shown increasing importance in the literature based on associations with current and future stroke events, dementia and cognitive decline. We hypothesize that the proton-density image, SNAP Ref, that is generated with Simultaneous Non-contrast Angiography and intraPlaque hemorrhage (SNAP) can more adequately assess calcifications compared to 3D TOF MRA relative to the reference standard, thin slice CTA.
