Studies of tau PET have frequently demonstrated an increased uptake in the dentate nucleus, compatible with post-mortem analyses.48,147 This has been shown in studies using a range of ligands including 18F-flortaucipir,33,48,147,151,152,154,155,218 18F-PI-2620,157 11C-PBB3150 and 18F-FDDNP.156 As noted previously, the majority have focused on 18F-flortaucipir, which has important interpretive limitations in PSP. Here, MAPT is linked to supranuclear palsy, progressive, 1.
