Harmonization of Flortaucipir, MK6240, PI2620 and RO948 with the Uniτ scale
Our results indicate that tau PET tracers can be harmonized to a common scale using a large head-to-head dataset. The Uniτ scale can harmonize entire 3D tau PET images, suggesting that there is no need to use pre-established ROIs, which would constrain the analysis to a few brain regions. Uniτ is freely accessible across platforms (www.unitau.app) for ROI and 3D tau PET harmonization.
