ADC, ADC ratios, FA, and FA ratios of lymphoma and GBM
| Variable | Lymphoma | GBM | P | 95% CI |
|---|---|---|---|---|
| FA | 0.140 ± 0.024 | 0.229 ± 0.069 | .001 | −0.137 to −0.040 |
| FA ratios | 0.25 ± 0.04 | 0.40 ± 0.12 | .002 | −0.234 to −0.064 |
| ADC (×10−3 mm2/s) | 0.630 ± 0.155 | 0.963 ± 0.119 | <.001 | −0.463 to −0.203 |
| ADC ratios | 0.83 ± 0.14 | 1.26 ± 0.13 | <.001 | −0.558 to −0.304 |
Note:—Data are the mean ± SD. FA indicates fractional anisotropy; ADC, apparent diffusion coefficient; GBM, glioblastoma multiforme; CI, confidence interval. ADC and FA ratios were calculated by dividing the mean ADC or FA values of the affected hemisphere by those of the normal-appearing white matter of the contralateral hemisphere.
