The Role of 11C-Choline PET Imaging in the Early Detection of Recurrence in Surgically Treated Prostate Cancer Patients With Very Low PSA Level <0.5 ng/mL

Purpose This study aims to evaluate the role of 11C-choline PET/CT in patients with biochemical relapse after radical prostatectomy (RP) showing prostate-specific antigen (PSA) values lower than 0.5 ng/mL. Methods We performed 11C-choline PET/CT in 71 consecutive patients previously treated with RP showing PSA values lower than 0.5 ng/mL. 11C-Choline PET/CT was performed following standard procedure. 11C-Choline PET/CT–positive findings were...
