Abstract: | Distinctive patterns of early and late benign fibrosis are commonly observed after stereotactic ablative radiotherapy for lung malignancies. These changes on computed tomography scans need to be distinguished from so-called high-risk radiological features, which can be associated with a higher risk for tumor recurrence. This pictorial report illustrates the different radiological changes seen after stereotactic ablative radiotherapy delivered by using volumetric modulated radiotherapy, a technique that is being increasingly used in clinical care. |
