Definition
Positron emission tomography (PET) is a functional imaging technique that allows the exploration of brain and body metabolic processes. The technique is based on the administration of a biologically active molecule labeled with a radioactive isotope (tracer). The signal produced by the tracer agent is detected by a gamma camera and reconstructed to generate a 3D image. In order to improve anatomical localization, PET imaging is usually associated to the acquisition, during the same session, of a morphological scan (positron emission tomography-computed tomography (PET-CT), or, more recently, positron emission tomography-magnetic resonance (PET-MR) (Aiello et al. 2016).
