The uptake of [18F]F-PSMA-1007 and [18F]F-PSMA-617-NODA ([18F]1) was compared in vivo in a xenograft model of human prostate cancer obtained using LNCaP cells which are PSMA positive, as confirmed by real time PCR-analysis (Additional file 1: S69A). This evidence concerns the gene FOLH1 and prostate cancer.
