  Abstract:  Positron Emission Tomography (PET) is a powerful nuclear medicine technique. Nuclear medicine techniques allow the visualization of physiological phenomena in vivo, and most important in a non-invasive way, through an external detection. The steps required in PET are the following: synthesis of labeled molecules; administration of these labeled molecules to the subject; scanning process with PET camera; data acquisition and subsequent processing; and finally image assessment. The goal of this paper is to briefly review the essential aspects concerning the PET technique, focusing on its principles and characteristics.
