FAP and lung neoplasm: We aimed to evaluate the feasibility of using [68Ga]Ga-FAPI-RGD, a dual-targeting heterodimeric PET tracer that recognizes both fibroblast activation protein (FAP) and integrin αvβ3 for detecting lung neoplasms, by comparing it with [18F]FDG and single-targeting tracers [68Ga]Ga-RGD and [68Ga]Ga-FAPI.
