Increased basal ganglia binding of 18F-AV-1451 in patients with progressive supranuclear palsy
Background: Progressive supranuclear palsy (PSP) is difficult to diagnose accurately. The recently developed tau PET tracers may improve the diagnostic work-up of PSP. Methods: Regional tau accumulation was studied using 18F-AV-1451 PET in 11 patients with PSP and 11 age-matched healthy controls in the Swedish BioFinder study. Results: 18F-AV-1451 standard uptake volume ratios were significantly h
