Cerebellar cortical amyloid deposition biases 18F-Florbetapir PET quantification with whole cerebellum as reference region.
OBJECTIVE To investigate whether cerebellar cortical amyloid-beta (Aβ) deposition biases 18F-Florbetapir Aβ PET quantification when the whole cerebellum (WC) is used as the reference region, and to identify a stable reference region for quantification. Additionally, to establish an optimal diagnostic threshold for the...
