FDG PET of Infection and Inflammation

Nuclear medicine plays an important role in the evaluation of infection and inflammation. Fluorine 18 fluorodeoxyglucose (FDG) is a readily available radiotracer that offers rapid, exquisitely sensitive high-resolution tomography. In patients with acquired immunodeficiency syndrome, FDG positron emission tomography (PET) accurately helps localize foci of infection and is particularly useful for differentiating central nervous system lymphoma...
