Regardless, [18F]AlF-PSMA-11 vs. [68Ga]Ga-PSMA-11 uptake in PSMA expressing LS174T-PSMA tumours was highest at 2 h p.i. (10.8 ± 2.3 vs 7.9 ± 1.3%ID/g), uptake in the bone was 5.0 ± 0.6 vs 0.1 ± 0.0%ID/g and renal uptake of [18F]AlF-PSMA-11 was lower than [68Ga]Ga-PSMA-11 (Lütje et al. 2019). Here, FOLH1 is linked to neoplasm.
