Abstract
The Alzheimer disease (AD) brain is characterized microscopically by the presence of extracellular amyloid plaques and intraneuronal neurofibrillary tangles consisting of phosphorylated tau aggregations. 18 F-THK5351 is a first-generation PET tau tracer that also binds to monoamine oxidase B, which represents astrogliosis, and is useful to evaluate some non-AD neurodegenerative disorders. We examined the utility of 18 F-THK5351 in preclinical AD using 3-dimensional stereotactic surface projection images optimized for its pathological accumulation by comparison with a normal dataset. By using this 18 F-THK5351 3-dimensional stereotactic surface projection procedure, which can evaluate phosphorylated tau and neuroinflammation, we could diagnose preclinical AD effectively.
