In Vivo Head‐To‐Head Comparison of [18F]GTP1 and [18F]PI2620 in Alzheimer’s Disease

Several radiotracers targeting tau pathology in Alzheimer’s disease (AD) are being used in human studies. Although abundant imaging characterization data exist for individual tracers there are only sparse in vivo data directly comparing tracers in head‐to‐head studies. As the use of tau PET increases, it is of paramount importance to enable multi‐tracer, multi‐center, multi‐national observational and therapeutic trials. We present the direct in vivo comparison of [18F]GTP1 and [18F]PI2620.
