The preliminary results of this study demonstrate the high potential of Cu-PSMA ligand PET/CT imaging in patients with recurrent disease and in the primary staging of selected patients with progressive local disease. The acquired PET images showed an excellent resolution of the detected lesions with very high lesion-to- background contrast. Furthermore, the long half-life ofCu allows distribution of the tracer to clinical PET centers that lack radiochemistry facilities for the preparation of Ga-PSMA ligand (satellite concept).

The preliminary results of this study show a high uptake of (64)CuCl2 in PC and involved regional lymph nodes indicating to a great potential of (64)CuCl2 PET/CT for primary staging of patients with prostate cancer.
