Fig. 5. ADC values according to stages. ADC increased from the early stage (p<0.001). ADC is increased if there is HSIC (p=0.031) in glioma III/IV. p-values are marked in the graph after the Mann–Whitney U test. ADC, apparent diffusion coefficient; FLAIR, fluid attenuated inversion recovery; HSIC, high signal change at the level of the internal capsule in FLAIR magnetic resonance imaging.
