The goal of this study is to investigate and compare [18F]PSMA-1007 PET/CT (18F-PSMA) and [68Ga]Ga-PSMA-11 PET/CT (68Ga-PSMA) for the primary staging of PC patients and to distinguish between low- and intermediate-risk versus (vs.)high-risk PC as well as between low- and intermediate-favorable risk vs. intermediate-unfavorable and high-risk PC, using the best maximum standardized uptake value (SUVmax) cut-off value to identify clinically significant PC foci. The gene discussed is FOLH1; the disease is pachyonychia congenita.
