Mean scores and ranges of DWI signal intensities (SIs) in cerebral gliomas according to the five-point visual assessment scale used in this study
| b = 1000 s/mm2 | b = 3000 s/mm2 | |||
|---|---|---|---|---|
| Mean ± SD | Range | Mean ± SD | Range | |
| High-grade glioma (n = 49) | 4.7 ± 0.5 | 4–5 | 4.6 ± 0.8 | 2–5 |
| WHO grade III (n = 20) | 4.7 ± 0.5 | 4–5 | 4.4 ± 1.0 | 2–5 |
| WHO grade IV (n = 29) | 4.7 ± 0.4 | 4–5 | 4.7 ± 0.7 | 3–5 |
| Low-grade (II) glioma (n = 13) | 3.7 ± 1.0 | 2–5 | 2.7 ± 1.3 | 1–5 |
