The odds ratio data in parentheses are 95% confidence intervals. P value with * mean statistical significance. D, true diffusion coefficient (×10⁻³ mm²/s); f, perfusion fraction (×10²%); D^*, fast diffusion coefficient (×10⁻³ mm²/s); K, kurtosis value (dimensionless); ADC, apparent diffusion coefficient (×10⁻³ mm²/s).
