Intensity modulated radiotherapy of non-small-cell lung cancer incorporating SPECT ventilation imaging

Purpose: The authors performed this retrospective study to investigate the impact of using ventilation scans obtained from single photon emission computed tomography (SPECT) in selecting beam directions in intensity modulated radiation therapy (IMRT) planning in lung cancer radiotherapy to spare dosimetrically well ventilated lung. Methods: For ten consecutive stage III non-small-cell lung cancer patients, the authors obtained both...
