Taking into account the results of the in vitro assessment, only the EuE-based ligands 68Ga-19F-rhPSMA-7 to -10 were evaluated in biodistribution studies in male LNCaP tumor–bearing CB17 SCID mice at 1 h after injection and compared with the biodistribution of 18F-DCFPyL and 18F-PSMA-1007 (Fig. 4 and Supplemental Table 2) (30). This evidence concerns the gene FOLH1 and neoplasm.
