Fig. 6From: CT patterns and serial CT Changes in lung Cancer patients post stereotactic body radiotherapy (SBRT)SBRT-treated lung cancer demonstrates stabilization at 35 months: a) Isodose multiplanar images for planning. b) Pre-SBRT CT shows a part-solid nodule. c) The nodule slightly decreased in size 9 months post-SBRT. d) 13 mo post-SBRT, the overall volume of the surrounding radiation changes obscuring the nodule increased in size with a pattern resembling “peribronchial consolidation”. e) 23 mo post-SBRT, the radiation changes decreased in size demonstrating a “scar-like” pattern and f) in 35 mo, there was stabilization of the “scar-like” pattern. g) 48 mo post-SBRT there was no change. Coronal (h) and sagittal (i) reconstruction at 48 mo (same time point as in fig. 5f) shows “scar-like pattern” after stabilization. The “width” of the lesion is small in 2 of the 3 planes (axial (g) and coronal (h)) compared to the third plane (sagittal (i)). To correctly identify the “scar-like pattern” careful evaluation of all 3 planes is needed as the lesion usually looks “bulkier” in one plane giving the false impression of a more “mass-like” patternBack to article page
