Study Description: This randomized phase II trial studies how well positron emission tomography (PET)/computed tomography (CT) scan work in guiding radiation therapy compared to standard radiation therapy treatment in patients with stage III non-small cell lung cancer. Imaging procedures, such as PET scan and CT scan, may help doctors plan radiation therapy for patients with non-small cell lung cancer.
