From: CT patterns and serial CT Changes in lung Cancer patients post stereotactic body radiotherapy (SBRT)
SBRT-treated lung cancer continues to decrease in size at 49 months: a) Isodose multiplanar images for planning. b) pre-SBRT CT shows a solid nodule. c) 6 mo post-SBRT, the primary lesion slightly decreases in size and there is mild adjacent peribronchial consolidation. d) 9 mo post-SBRT, the lesion significantly increases in overall size with mild surrounding peribronchial consolidation. e) 18 mo post-SBRT, the lesion size is unchanged and there is improvement of the surrounding peribronchial consolidation, f) 22 mo post-SBRT, there is mild decrease of the lesion size and resolution of surrounding peribronchial consolidation, g) 49 mo post-SBRT, there is further mild decrease in lesion size
