Biopsy findings in PET/CT-positive lung lesions in a community hospital.

Unlabelled: An investigation was undertaken to determine the significance of fluorodeoxyglucose (FDG) uptake in lung abnormalities on positron emission tomography / computed tomography (PET/CT) in our practice. Factors such as lesion size, standard uptake value (SUV), multiplicity of pulmonary parenchymal abnormalities, and the presence of FDG uptake in mediastinal and hilar lymph nodes were analyzed as possible predictors of benign or malignant etiology.

Methods: PET/CT reports from 5/20/02 to 6/1/03 were reviewed, and 263 patients with significant FDG uptake (maximum SUV > or = 2.
