What is a PET-CT scan?
Positron emission tomography coupled with a CT scan (PET-CT) is a medical imaging method used by nuclear medicine departments. It enables the metabolic or molecular activity of an organ to be measured in three dimensions thanks to the emissions produced by the positrons from a radioactive product injected beforehand. These images are then merged with a scan (CT) so as to provide precise localisation for the examination.
PET scans are based on the general principle of scintigraphy, which consists of injecting a tracer with known biological properties and behaviour to obtain an image of the functioning of an organ or the presence of a molecular target. This tracer is marked by a radioactive atom (mainly Fluorine 18) which emits positrons whose annihilation produces two photons. The simultaneous detection of these photons enables the localisation of the site of their emission as well as the concentration of the tracer at each point of the organ. It is this quantitative information that is represented in the form of an image displaying the areas of high tracer concentration in colour.
