Right upper lobe clinical stage IA NSCLC treatment planning PET/CT with a tumor SUV max of 10.5 (A), planned radiation dose distribution (B: the planning treatment volume receiving 45 Gy shown in red and the 30 Gy isodose line in blue), and PET/CT at 6, 12, and 18 months post-treatment (C, D and E) show an initial decrease in tumor SUV max to 1.5 followed by a transient radiation induced increase (tumor SUV max = 4.0) which resolves by 18 months (tumor SUV max = 2.5).
