Zhou et al. [4] also demonstrated the superiority of radiolabeled Cho PET/CT compared to bone scintigraphy in this setting; however, radiolabeled Cho PET/CT showed a slightly lower diagnostic accuracy compared to PET/CT with PSMA-targeted agents and 18F-NaF for detecting bone metastases of PCa. The gene discussed is FOLH1; the disease is posterior cortical atrophy.
