Validation of [68Ga]Ga-PSMA-Tz with PET imaging. A Radiosynthesis of [68Ga]Ga-PSMA-Tz. B MicroPET imaging of 22Rv1 xenograft models (n = 3) after injection of [68Ga]Ga-PSMA-Tz. Unlabeled PSMA617 was used as a blocking ligand. The tumor uptakes at 120 min p.i. (C), the tissue uptakes of main organs (D), and tumor/tissue ratios (E) were derived from the PET images
