Direct region of interest comparisons between PET tracers. Across 16 Alzheimer’s disease patients, regions with greater 18F-AV1451 uptake were strongly associated with lower 18F-FDG metabolism (A). Modest, positive associations were also observed between 11C-PiB and 18F-FDG (B) and between 18F-AV1451 and 11C-PiB (C).
