1 Combined Analysis of V20, VS5, Pulmonary Fibrosis Score on Baseline Computed Tomography, and Patient Age Improves Prediction of Severe Radiation Pneumonitis After Concurrent Chemoradiotherapy for Locally Advanced Non–Small-Cell Lung Cancer  Kayoko Tsujino, MD, PhD, Tomohisa Hashimoto, MD, Temiko Shimada, MD, PhD, Eisaku Yoden, MD, PhD, Osamu Fujii, MD, PhD, Yosuke Ota, MD, Miyako Satouchi, MD, PhD, Shunichi Negoro, MD, Shuji Adachi, MD, PhD, Toshinori Soejima, MD, PhD  Journal of Thoracic Oncology  Volume 9, Issue 7, Pages (July 2014) DOI: /JTO Copyright © 2014 International Association for the Study of Lung Cancer Terms and Conditions

2 FIGURE 1 Definition of the computed tomography (CT) scoring system together with specific examples. The score can be determined when at least one lobe shows the relevant CT findings. A) Pulmonary fibrosis score and typical examples of scores 1, 2, and 3. B) Pulmonary emphysema score and typical examples of scores 2, 3, and 4.
