ABSTRACT
Positron emission tomography/computed tomography (PET/CT) using fluorine-18 labelled fluorodeoxyglucose (FDG) is a powerful tool for managing patients with suspected lung nodules and lung cancer. In this review, we discuss the utility of FDG PET/CT imaging in evaluation of suspected pulmonary nodules and initial staging of patients with newly diagnosed lung cancer, prognostic value of quantitative PET parameters, technical developments in PET imaging such as hybrid PET/magnetic resonance systems, and the use of other PET radiopharmaceuticals related to lung cancer pathophysiology.
