PSMA PET/CT quick procedure guide

Abstract

The application of PET/CT with radiopharmaceuticals targeting PSMA is significantly transforming the diagnostic and therapeutic strategies of patients with prostate cancer. In Spain, the availability and access to positron-emitting radiopharmaceuticals targeting Prostate-Specific Membrane Antigen (PSMA) have significantly changed in recent months. These changes are affecting their use in diagnostic procedures. As a result, its use within diagnostic protocols for patients with prostate cancer is undergoing significant modifications. In this collective and cooperative document, the authors have selected the most robust evidence accumulated to date to generate a clinical guide to achieve appropriate use of this technology. A format that presents the most frequent clinical situations and the patient profiles in which PSMA PET/CT plays a significant role or will do so in the immediate future has been chosen. It should be taken into account that regulatory restrictions mediate the current indications for its use in Spain, as well as its current cost and the production capacity of radiopharmaceuticals. The guideline presents a review of the established methodology for optimized imaging with each of the radiopharmaceutical variants targeting PSMA and recommendations for structured and accurate reporting of metabolic findings in combination with CT.
