FOLH1 and neoplasm: PSMA-directed positron emission tomography/computed tomography (PET/CT) with different tracers such as [68Ga]Ga-PSMA-11, [68Ga]Ga-PSMA I&T or [18F]PSMA-1007 has been established in diagnostics, especially in primary staging and in the localization of biochemical recurrence (BCR) enabling a highly accurate and early localization of the tumor lesions [10–13].
