FAP and renal cell carcinoma: The aim of this study is to evaluate a novel radiopharmaceutical [18F]AlF-NOTA-FAPI-RGD (denoted as [18F]AlF-LNC1007), a dual-targeting heterodimer tracer targeting both FAP and integrin αvβ3, and to compare the diagnostic value of [18F]AlF-LNC1007 with [18F]FDG and [18F]AlF-NOTA-FAPI-04 PET/CT in RCC.
