Comparison of mean DWI signal intensity (SI) ratios and standard deviations between b = 1000 s/mm2 and b = 3000 s/mm2 in high-grade and low-grade gliomas
| SI Ratio b = 1000 s/mm2 | SI Ratio b = 3000 s/mm2 | |
|---|---|---|
| High-grade glioma (n = 49) | 1.96 ± 0.57 | 2.13 ± 1.05 |
| WHO grade III (n = 20) | 1.91 ± 0.56 | 2.12 ± 1.17 |
| WHO grade IV (n = 29) | 1.99 ± 0.59 | 2.14 ± 0.97 |
| Low-grade (II) glioma (n = 13) | 1.39 ± 0.43 | 0.83 ± 0.50 |
