The cells with bold-face type and with gray-shaded color are those with significant correlation as indicated by Spearman’s rank correlation.

ADC: Apparent Diffusion Coefficient (DWI); CBV: Cerebral Blood Volume (DSC-MRI); D: True diffusion coefficient (IVIM);

D*: Pseudo-diffusion coefficient (IVIM); f: perfusion fraction (IVIM); K: Diffusion Kurtosis; MD: Mean Diffusivity (DTI); FA: Fractional Anisotropy (FA); P: Pure isotropic diffusion coefficient (DTI); Q: Pure anisotropic diffusion coefficient (DTI); PD: Proton Density (T2-relaxometry); T2: T2 relaxation time (T2-relaxometry); T1_SUB: Subtracted high-resolution T1w from the corresponding high-resolution contrast-enhanced T1w image; T2_ISO: High-resolution T2w image; FLAIR: Fluid-attenuated inversion recovery image.
