DOCUMENT INFO
Description: Introduction PET-CT, a relatively new imasing technique combining positron emission tomography (PET) with computerised tomography (CT), uses an intravenous injection of 2-18F-fluoro-2-deoxy-D-glucose (FDG), a radioactively tagged form of glucose, and tracks its distribution around the body. [...] accurate localisation using PET-CT can prevent such misinterpretation19. * Patient movement between the formation of the individual PET and CT scans can create significant artefacts, leading to a 'mismatch' between images and consequent uncertainty of the precise anatomical site of increased FDG uptake.
