FOLH1 and neoplasm: In a study with 37 patients with biochemical relapses of PCa who were evaluated with [68Ga]Ga-PSMA-11 and [18F]F-fluoromethylcholine PET/Computed Tomography (CT), the former presented a higher detection rate (78 lesions in 32 patients versus 56 lesions in 26 patients; all of these lesions were also detected with [68Ga]Ga-PSMA-11), as well as images with higher SUVmax and increased contrast (tumor-to-background ratio) in most of the lesions [22].
