After 24 h, tumor/liver ratio of [89Zr]-PSMA-DFO was significantly higher than after 2 h and 4 h, and significantly higher than tumor/liver ratio of [68Ga]Ga-PSMA-11 and [18F]F-JK-PSMA-7 at 2 h and [18F]F-JK-PSMA-7 at 4 h (F(6,20) = 102.3; p < 0.0001, post hoc p < 0.05). This evidence concerns the gene FOLH1 and neoplasm.
