Molecular Imaging in Neuroendocrine Differentiation of Prostate Cancer Ga-68-PSMA Versus Ga-68-DOTA NOC PET-CT

摘要

We report on a 62-year-old man with metastatic prostate cancer (cT3b N1) diagnosed in 2011, treated with total androgen blockage with flutamide and goserelin acetate (Zoladex). He presented with left suprascapular swelling and low-back pain after being asymptomatic for 5 years. His prostate-specific antigen was 0.049 ng/mL. F-18-NaF PET-CT and Ga-68-PSMA scan were negative, whereas Ga-68-DOTA NOC scan done after 10 days showed multiple somatostatin-avid hepatic and lymph node metastasis.
