New Enhancement beyond Radiation Field Improves Survival Prediction in Patients with Post-Treatment High-Grade Glioma

Figure 4

Example of patient without NERF. A 63-year-old male with pathologically confirmed anaplastic astrocytoma in the right temporal lobe. His OS was 790 days. Axial contrast-enhanced T1-weighted image 72 h after resection (a). Axial contrast-enhanced CT image with treatment-planning overlay shows the volumes treated with 60 Gy (red outline) and 50 Gy (yellow outline) (b). There was no new developed enhancing lesion within and outside radiation field in follow-up MRI 6 months after completion of radiotherapy (c). NERF, new enhancement beyond the radiation field.
