Although both 2-[18F]FGlc-PSMA and 6-[18F]FGlc-PSMA displayed 2- to 3-fold higher tumor uptake than [68Ga]Ga-PSMA-11 in a direct comparison study, it was 6-[18F]FGlc-PSMA that showed a 10-fold lower kidney accumulation with rapid clearance through the urinary tract. Here, FOLH1 is linked to neoplasm.
