Table 4:

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
