Table 2 Table with the statistics of the T2 values from all the patients per region of interest (ROI). The ROIs correspond to normal white matter (nWM), T2-hyperintensity (T2h), T1w-enhancement (T1e) and perilesional area (PER). Column 3: Mean over patients of the T2 ROI statistics. Column 4: 95% CI of the mean over patients of the T2 ROI statistics. Column 5: P-values of the Wilcoxon signed-rank test with the nWM (P-val ROI vs. nWM). Column 6: P-values of the Wilcoxon signed-rank test with the abnormal tissue without T1w-enhancement (P-val ROI vs. T2h). Column 7: P-values of the Wilcoxon signed-rank test with the T1w-enhancement voxels (P-val ROI vs. T1e).
