From: CT patterns and serial CT Changes in lung Cancer patients post stereotactic body radiotherapy (SBRT)
SBRT-treated lung cancer demonstrates local recurrence at 5 years: a) Isodose multiplanar images for planning. b) pre-SBRT, CT shows a solid nodule (black arrow). Axial (c) and coronal plane (d) chest CT 3 years post-SBRT show “modified conventional pattern” that has stabilized. 5 years post-SBRT axial (e) and coronal (f) images show increased soft tissue density bulging on one side of the lesion (posteriorly on axial plane and superiorly on coronal plane, black arrows) in keeping with local recurrence
