Primary outcomePrimary: Diagnostic Performance Metrics (Sensitivity, Specificity, PPV, NPV, and Accuracy) of Ultrasonography and Capnography for Malignant Lung Nodules — 100; 70; 100; 100 percentage — p=0.02
Summary
This phase II trial studies how well 18F-FSPG positron emission tomography (PET)/computed tomography (CT) work in diagnosing early lung cancer in patients with indeterminate lung nodules. PET imaging with an imaging agent called 18F-FDG is often used in combination with a PET/CT scanner to evaluate cancers. Giving 18F-FSPG before a PET/CT scan may work better in helping researchers diagnose early lung cancer in patients with lung nodules.
