Abstract

INTRODUCTION: The introduction of tau imaging agents such as (18)F-THK523 offers new hope for the in vivo assessment of tau deposition in tauopathies such as Alzheimer's disease (AD), where preliminary (18)F-THK523-PET studies have demonstrated significantly higher cortical retention of (18)F-THK523 in AD compared to age-matched healthy individuals. In addition to AD, tau imaging with PET may also be of value in assessing non-AD tauopathies, such as corticobasal degeneration (CBD), progressive supranuclear palsy (PSP) and Pick's disease (PiD). METHODS: To further investigate the ability of THK523 to recognize tau lesions, we undertook immunohistochemical and fluorescence studies in serial br..
