Popis: The detection of lesions in the context of biochemical recurrence of prostate cancer is a major challenge for all imaging modalities. Recently, the prostate-specific membrane antigen (PSMA) is recognized as a novel target for the PET–CT (positron emission tomography–computed tomography) imaging of prostate cancer with the tracer 68Ga-PSMA (68Gallium-labelled PSMA), mainly in the detection of relapses and metastasis. PSMA PET–CT imaging shows high tracer uptake at the sites of primary tumor and lymph node, and bone metastasis in direct correlation with aggressiveness and Gleason scores. PSMA PET–CT seems to be a highly accurate imaging tool for restaging of prostate cancer patients with biochemical recurrence, and it proved to be clearly superior in detecting prostate cancer lesions at low PSA levels when compared to other methods.
