[68Ga]Ga-FAPI-PSMA was shown to achieve superior tumor uptake (SUVmax = 1.67 for U87 MG tumor xenografts; SUVmax = 1.32 for 22Rv1 tumor xenografts) when compared to those of the monospecific tracers, [68Ga]Ga-FAPI-04 (SUVmax = 0.45 for U87 MG tumor xenografts) and [68Ga]Ga-PSMA-617 (SUVmax = 0.25 for 22Rv1 tumor xenografts). This evidence concerns the gene FOLH1 and neoplasm.
