FAP and neoplasm: Compared with three of our previously reported bispecific PSMA/FAP tracers ([68Ga]Ga-AV01017, [68Ga]Ga-AV01030, and [68Ga]Ga-AV01038), both [68Ga]Ga-AV01084 and Ga-AV01088 have better PSMA-binding affinity and improved tumor uptake in PSMA-expressing xenografts and tumor-to-background (blood, muscle, and bone) contrast ratios.
