TABLE 1.

Comparison of the ADC Values and Ki-67 Proliferation Index Between Low-Grade and High-Grade Gliomas

Low-Grade Group (n = 87) High-Grade Group (n = 34) P Value
ADCmean (×10−3 mm2/s) 1.387 ± 0.206 1.096 ± 0.122 <0.001
ADCmin (×10−3 mm2/s) 1.121 ± 0.130 0.884 ± 0.080 <0.001
ADC ratio 1.614 ± 0.258 1.280 ± 0.139 <0.001
Ki-67 3.701 ± 3.751 20.323 ± 13.153 <0.001

ADC indicates apparent diffusion coefficient; ADC ratio, tumor/normal brain ADC ratio; ADCmean, mean apparent diffusion coefficient; ADCmin, minimum apparent diffusion coefficient.
