A 73-year-old man with AD, Mini Mental State Examination (MMSE) 23/30. Fluorodeoxyglucose PET/CT (a) demonstrates hypometabolism involving the bilateral parietal lobes (arrows) and precuneus and PCC (oval). Flortaucipir PET/CT (b) shows tau retention in the bilateral parietal lobes (arrows) and precuneus and PCC (oval), mirroring the regions of hypometabolism. Florbetapir PET/CT (c) demonstrates diffuse cortical uptake with “kissing hemispheres.” Arterial spin labeling (d) demonstrates hypoperfusion to the bilateral parietal lobes (arrows), similar to the FDG-PET/CT
