18F-fluorodeoxyglucose positron emission tomography/ computed tomography imaging review of benign lesions of the thorax

2-deoxy-2-(Fluorine-18) fluoro-D-glucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) has been used exclusively to diagnose malignancies. However, increased 18F-FDG uptake is not always limited to malignant lesions. This imaging review demonstrates the physiological 18F-FDG uptake of normal structures in the thorax and illustrates many benign pathological lesions with standardized uptake value >2.5. These various...
