FOLH1 and hepatocellular carcinoma: Whereas in two patients HCC uptake was both FDG and 68Ga-PSMA-HBED-CC PET negative, FDG uptake proved higher than that of the PSMA-targeting ligand (both visually and quantitatively (SUVmax)) in four patients (one of these patients being FDG negative), whereas in nine patients Ga-PSMA-HEBD-CC uptake by their HCC proved higher when compared to that of FDG (respectively negative in two patients).
