Alzheimer's disease (AD) is a type of dementia that exhibits decreased perfusion-metabolism and GM loss in the brain. This work examines the correlation between both rCBF-ASL and FDG-PET in a group of 24 subjects. In addition, ASL was utilized in a second group of 99 subjects (Control, MCI and AD) to assess hypoperfusion in AD. Significant correlation between rCBF and FDG-PET was found. Hypoperfusion patterns were seen in posterior cingulate and posterior lobes in AD. This work demonstrates both: a high correlation between ASL and FDG-PET, and the capability of ASL to become a promising technique to monitor the AD.
