Ga-68-labeled urea-based PSMA inhibitor (Ga-68-PSMA-HBED-CC) is a novel positron emission tomography (PET) tracer for staging of prostate cancer patients with a high accuracy for detection of lymph node and organ metastasis, as well as for detection of residual or recurrent local disease [5]. The gene discussed is FOLH1; the disease is prostate cancer.
