Mean and its 95% confidence interval (CI) over subjects in the respective group (T1w-enhancement or no T1w-enhancement) of the region of interest (ROI) statistics of the abnormal tissue for T1 values, T2 values, the Euclidian norm of the T1 and T2 values (normT1T2) and the Euclidian norm of the logarithm of the T1 and T2 values (normlog). The last column gives the P-values of the Wilcoxon signed-rank test between the patient groups.
