Abstract

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.

PET imaging with a [68 Ga]gallium-labelled PSMA ligand for the diagnosis of prostate cancer: biodistribution in humans and first evaluation of tumour lesions. Eur J Nucl Med Mol Imaging. 2013; 40(4):486–95. The importance of this study was to establish a normal pattern of concentration of PSMA in different segments and to evaluate its applicability for tumour imaging by calculating the ratio between radiotracer uptake in tumour lesions and background.

(2015);42(2):197–209. 68 Ga-PSMA-ligand PET/CT can detect prostate cancer in a high percentage of patients with suspected neoplasm (82.8%). Any uptake of 68 Ga-PSMA-HBED-CC in lesions above local background is highly specific for prostate cancer and must therefore be regarded as prostate cancer unless otherwise proven. This article provides an analysis of the diagnostic value of 68 Ga-PSMA-ligand PETCT in a large cohort and the influence of several possibly interacting variables.
