- FIG 1.
A, nODI (ODI pt/ODI HC) values within DAWM, GEL, NAWM, and NGEL masks at baseline with a respective 2-sided t test. Only statistically significant differences are reported (asterisk = P < .05; 2 asterisks = P < .005; 3 asterisks = P < .0005). B, Receiver operating characteristic for logistic regression using nODI for discriminating between GELs and NGELs at baseline. C, NDI values within DAWM, GELs, HCWM, NAWM, and NGELs at baseline with respective 2-sided t-tests. Only statistically significant differences are reported (asterisk = P < .05; 2 asterisks = P < .005; 3 asterisks = P < .0005). pt, subject.

Lesion type 1 NODDI color map8 graphically representing NDI (green) or VEC (red) compartment prevalence in voxels within a focal WM lesion (white arrows) at baseline (A–C) and at follow-up (after 12 months) (D–F). The green within the lesion is represented more at follow-up, after the disappearance of the enhancement, with a relative decrease of the red voxels. FLAIR sequences (C and F) show an important reduction in size with time. VEC and NDI are fractions in each voxel: If NDI increases, VEC decreases and vice versa. FISO indicates isotropic volume fraction.

Lesion type 2 NODDI color map8 graphically representing NDI (green) or VEC (red) compartment prevalence in voxels within a focal WM lesion (white arrows) at baseline (A–C) and at follow-up (after 15 months) (D–F). The green within the lesion is less represented at follow-up after the disappearance of the enhancement, with a relative increase of the red voxels. FLAIR sequences (C and F) show a moderate reduction in size with time. VEC and NDI are fractions in each voxel: If NDI decreases, VEC increases and vice versa. FISO indicates isotropic volume fraction.
