ATN Radionuclide Imaging in Dementia: Amyloid, Tau, and FDG PET

Abstract

In the field of imaging diagnosis of dementia, the concept of imaging biomarkers has proposed the research criteria of ATN classification corresponding to amyloid （A）, tau （T）, and neurodegeneration （N）. The use of amyloid PET （A）, tau PET （T）, and FDG cerebral glucose metabolism PET （N） as imaging biomarkers will enable ATN classifica tion and is expected to contribute to the differential diagnosis of dementia and the elucidation of the progression process of Alzheimerʼs disease.
