|Cigarette Smoker Current Smoker Former Smoker Multiple Pulmonary Nodules Pulmonary Nodule||Procedure: Computed Tomography Drug: Fludeoxyglucose F-18 Drug: Fluorine F 18 L-glutamate Derivative BAY94-9392 Procedure: Positron Emission Tomography||Phase 2|
I. Comparison of fluorine F 18 L-glutamate derivative BAY94-9392 (18F-FSPG) accumulation with fludeoxyglucose F-18 (18F-FDG) accumulation to assess whether (4S)-4-(3-18F-Fluoropropyl)-L-Glutamate (18F-FSPG)-PET is better at discriminating between benign and malignant nodules.
I. To develop and validate early lung cancer detection biomarkers that would directly impact the growing need to integrate imaging and non-invasive molecular diagnostics for indeterminate pulmonary nodules and allow physicians to avoid unnecessary invasive procedures in patients with benign lung disease.
Patients receive 18F-FSPG intravenously (IV) and, undergo a PET/CT scan over 30-60 minutes. Within 24 hours-14 days, patients receive 18F-FDG and undergo a second PET/CT scan over 30-60 minutes.
After completion of study, patients are followed up within 24-72 hours.

Experimental: Diagnostic (18F-FSPG PET/CT, 18F-FDG PET/CT)
Patients receive 18F-FSPG IV and, undergo a PET/CT scan over 30-60 minutes. Within 24 hours-14 days, patients receive 18F-FDG IV and undergo a second PET/CT scan over 30-60 minutes.
Procedure: Computed Tomography
Drug: Fludeoxyglucose F-18
Drug: Fluorine F 18 L-glutamate Derivative BAY94-9392
Procedure: Positron Emission Tomography
- Fluorine F 18 L-glutamate derivative BAY94-9392 (18F-FSPG) specificity for malignant lung nodules [ Time Frame: Up to 5 years ]18F-FSPG accumulation in lung nodules will be assessed. The observed FSPG specificity will be assessed against a fixed value of 75%.
- Improved performance of prediction model for lung nodules [ Time Frame: Up to 5 years ]Improved performance is defined as a p < 0.05 increase in the C statistic determined using DeLong test for correlated receiver operating characteristic (ROC) curves.
