FOLH1 and posterior cortical atrophy: Positron emission tomography/computed tomography with ligands of the prostate-specific membrane antigen (PSMA PET/CT), especially with the 68Ga-labelled ligand PSMA-11, has been used widely to assess PCa metastases, particularly at the time of biochemical recurrence [5, 6], but 68Ga-PSMA PET/CT has also been shown to possess premium diagnostic accuracy for the detection of bone metastases at the time of primary staging [7, 8].
