In the setting of PCa staging, Schollhammer and colleagues reported a clinical case of a patient undergoing PET/CT scans with 68Ga-PSMA, 68Ga-RM2 and 18F-Choline, while Fassbender et al. used 68Ga-PSMA PET/CT and 68Ga-Ga-RM2 PET/MRI to study eight patients with a primary diagnosis of PCa [15,24]. This evidence concerns the gene FOLH1 and posterior cortical atrophy.
