To evaluate the role of computed tomography (CT) -guided needle biopsy and sodium iodide fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) in the investigation of solitary pulmonary nodules (SPN), which are discovered on screening chest radiographs, and to determine the cost-effectiveness of these modalities. ⋯ The introduction of CT-guided needle biopsy and FDG-PET for the evaluation of SPNs, which are discovered on screening chest radiograph, is potentially cost-effective in Japan with high accuracy.
