[18F]Flortaucipir (a.k.a. TauvidTM, [18F]AV-1451 or [18F]T807) tau-PET is widely used in AD due to its high specificity to paired helical filament tau pathology in AD, but relatively low affinity in other tauopathies like frontotemporal lobar degeneration, progressive supranuclear palsy, and corticobasal degeneration [3]. Here, MAPT is linked to corticobasal degeneration disorder.
