This two-part preclinical study aims to evaluate prostate specific membrane antigen (PSMA) as a valuable target for expression-based imaging applications and to determine changes in target binding in function of varying specific activities (SA) of 18F-AlF-PSMA-11. For the evaluation of PSMA expression levels, male NOD/SCID mice bearing prostate cancer (PCa) xenografts of C4-2 (PSMA+++), 22Rv1 (PSMA+) and PC-3 (PSMA-) were administered 18F-AlF-PSMA-11 with a medium SA (20.26 ± 3.25 MBq/µg). SUVmean and SUVmax values were respectively 3.22 and 3.17 times higher for the high vs low PSMA expressing tumors (p 18F-AlF-PSMA-11 imaging with a high (213.3 ± 39.3 MBq/µg) and/or low SA (1.94 ± 0.27 MBq/µg). SUV values showed a significantly increasing trend with higher SA. Significant changes were found for SUVmean and SUVmax between the high vs low SA and medium vs low SA (both p |
