18F-FDG PET/CT Imaging: Normal Variants, Pitfalls and Artefacts
In recent years, positron emission tomography (PET)/computed tomography (CT) has gained widespread clinical acceptance in oncology. It is being used extensively in the diagnosis, staging, restaging and therapy response evaluation of tumours along with several benign indications in cardiology and neurology. Fluorine-18 (18F) 2-fluoro-2-deoxy-D-glucose (FDG) is the most commonly used positron-emitting radiotracer in PET/CT studies. In this chapter, we will mainly focus on normal variants and artefacts in 18F-FDG PET/CT studies.
