Table 1 Grading system of edema and necrosis, (in analogy to [8])
From: Does age matter? - A MRI study on peritumoral edema in newly diagnosed primary glioblastoma
Grade | Edema |
|---|---|
0 | No edema |
1 | Minimal edema |
2 | Edema approximately equal to tumor area |
3 | Major edema greater than tumor area |
Grade | Necrosis |
0 | no necrosis |
1 | necrosis <25% of tumor area |
2 | necrosis 25-50% of tumor area |
3 | necrosis >50% of tumor area |
