1 Lung Perfusion Imaging Can Risk Stratify Lung Cancer Patients for the Development of Pulmonary Complications after Chemoradiation  Isis W. Gayed, MD, Joe Chang, MD, PhD, E Edmund Kim, MD, Rodolfo Nuñez, MD, Beth Chasen, MD, H Helen Liu, PhD, Katsuhiro Kobayashi, MD, Yujing Zhang, MD, Zhongxing Liao, MD, Salman Gohar, MD, Melinda Jeter, MD, Louise Henderson, PhD, William Erwin, MS, Ritsuko Komaki, MD  Journal of Thoracic Oncology  Volume 3, Issue 8, Pages (August 2008) DOI: /JTO.0b013e d5 Copyright © 2008 International Association for the Study of Lung Cancer Terms and Conditions

2 FIGURE 1 Coronal slices from lung perfusion SPECTs demonstrating A, Localized perfusion defect in the right upper lung (arrow) equivalent to a score of 1 on the LPS. B, Localized perfusion defect in the left lung equivalent to a score of 2 (short arrow) and in the right lung (long arrow) equivalent to a score of 3 on the LPS. C, Absent left lung after pneumonectomy equivalent to a score of 4 on the LPS.

3 FIGURE 2 Posterior planar images of the chest demonstrating different patterns of the remaining lung perfusion (A–D) that corresponds to the different points on the LPS (1–4). A, is homogeneous = score of 1, B, is mild heterogeneity = score of 2, C, is moderate heterogeneity = score of 3, D, is marked heterogeneity = score of 4.

4 FIGURE 3 Lung perfusion SPECT/CT in a patient with a small LUL cancer but poor perfusion in the remaining lung who developed respiratory failure after RT.
