Recent development of tau positron emission tomography(PET)ligands enables in vivo detection of cerebral tau pathologies, resulting in numerous clinical studies in Alzheimer’s disease(AD). Moreover, the tau PET ligands are shifting from the “first generation” to the “second generation” with improved their protein binding specificity and metabolic stability. On the other hand, it has become clear that there are differences among the ligands in their binding affinities to non-AD tauopathies such as frontotemporal lobar degeneration. Among the “second generation” tau PET ligands, [18F] PI-2620 and [18F] PM-PBB3(APN-1607)have been reported to be effective in PET visualization of tau pathologies in non-AD tauopathies. In this article, we will review the current status of tau PET ligand development and the findings of tau PET ligands in non-AD tauopathies to date.
