The results of this study showed good imaging of [18F]AlF-PSMA-11 in primary prostate lesions, lacrimal glands and salivary glands, with high uptake still observed in the delayed imaging performed at 120 min, indicating a favourable and stable biological distribution of [18F]AlF-PSMA-11 in target organs. This evidence concerns the gene FOLH1 and male reproductive organ cancer.
