Note:

IVIM: intravoxel incoherent motion, NIHSS: National Institutes of Health Stroke Scale, mRS: modified Rankin Scale. rADC, rD, rD*, rf and rfD*: The lesioned/contralateral ratios of apparent diffusion coefficient, true diffusion coefficient, pseudo-diffusion coefficient, perfusion fraction, and the product of f and D*. Statistical significance, p < 0.05.
