In addition, the performance of positron emission tomography (PET) molecular imaging with gallium-68 (68Ga) or fluorine-18 (18F) on prostate-specific membrane antigen (PSMA), which specifically targets PSMA peptides highly expressed on the surface of the prostate tumor cells and its accompanying metastases, allows noninvasive precise evaluation of prostate lesions. The gene discussed is FOLH1; the disease is prostate neoplasm.
