Noninvasively measuring the quantitative blood flow, ASL perfusion MRI can potentially be used as marker for progressive neurodegenerative disease like AD. Using the Alzheimers Disease Neuroimaging Initiative ASL data, we showed the first evidence of the sensitivity of ASL CBF to prodromal and early AD in a multi-site context; ASL CBF appeared to decrease inversely with degree of impairment which is consistent with prior work with FDG PET.
