| rD | 0.58 ± 0.14 | 0.43 ± 0.10 | 0.002 |
| rD* | 0.78 ± 0.27 | 0.55 ± 0.35 | 0.142 |
| rf | 0.76 ± 0.26 | 0.79 ± 0.30 | 0.702 |
| rfD* | 0.58 ± 0.27 | 0.40 ± 0.13 | 0.116 |
Note:
IVIM: intravoxel incoherent motion, 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*. Data are presented as mean ± standard deviation. Statistical significance, p < 0.05.
