Table 1. IVIM-derived parameters in the tumor sites in low- and high-grade gliomas.

	LGG	HGG	P-value*
ADC (×10−3 mm2 /sec)	0.906 ± 0.110	0.618 ± 0.142	0.000
D (×10−3 mm2 /sec)	0.756 ± 0.110	0.506 ± 0.117	0.000
D* (×10−3 mm2 /sec)	2.150 ± 0.423	2.706 ± 0.852	0.013
f	0.477 ± 0.130	0.290 ± 0.096	0.000

Note: LGG denotes low-grade gliomas, HGG denotes high-grade gliomas.

*The P values were the comparison of the parameters between low- and high- grade gliomas.
