The role of PSMA PET/CT imaging in restaging of prostate cancer patients with low prostate-specific antigen levels.

Introduction: Prostate-specific membrane antigen (PSMA) is increasingly being recognized as a novel target for the PET imaging of prostate cancer (PCa) and Ga-DKFZ-11 (Ga-PSMA) has been suggested as a novel tracer for detection of PCa relapses and metastases. The aim of this study was to evaluate the diagnostic value of PSMA PET/CT in the diagnosis of recurrent PCa with low prostate-specific antigen (PSA) levels.

Patients And Methods: We carried out a retrospective analysis of patients who underwent PSMA PET/CT from November 2013 to December 2014 in our department.
