Correlation analyses Correlations with disease duration As demonstrated in Table 3 , disease duration showed highly significant correlations with MD values in PU (r = 0.58; p<0.001), GP (r = 0.34; p<0.001), SN (r = 0.41; p<0.001), SL 2 (r = 0.33; p<0.001) and SL 3 (r = 0.25; p<0.001) as well as with R2* in SL 1 (r = -0.36; p<0.001).
