FOLH1 and posterior cortical atrophy: 68Ga-labeled prostate-specific membrane antigen (68Ga-PSMA) positron emission tomography/computed tomography (PET/CT) is a relatively new molecular imaging technique that shows superior performance to conventional imaging techniques in diagnosing and staging PCa, providing us with an opportunity to discriminate patients with csPCa (GS ≥ 7) from those with benign prostate diseases (BPD) 6, 7.
