Article Figures & Data

Figures

  • Figure 1
    Figure 1 Segmentation of lesional, perilesional, and normal-appearing white matter displayed on baseline T1 image

    Red represents lesion core, green represents lesion “rim,” perilesional white matter (PLWM) layers (layer 1 and layer 5) are yellow and magenta, and NAWM layer (layer 10) is blue. Layer number represents distance from the lesion in mm.

  • Figure 2
    Figure 2 The average T1 hypointensity profile (mean ± SD) normalized by T1 intensity in NAWM
  • Figure 3
    Figure 3 Correlation plots between PBVC and 5 individually significant variables

    (A) Baseline lesion volume (vertical scale units, mm3); (B) new lesion volume (vertical scale units, mm3); (C) baseline NAWM RD (vertical scale units, μm2/ms); (D) change in lesion MD (vertical scale units, μm2/ms); and (E) change in NAWM RD (vertical scale units, μm2/ms). Two parallel lines represent 95% CI. PBVC = percent brain volume change.

  • Figure 4
    Figure 4 Change of AD and RD in lesion core, lesion “rim,” perilesional, and normal-appearing white matter

    Error bars represent SE. AD = axial diffusivity; RD = radial diffusivity.

  • Figure 5
    Figure 5 PBVC linear regression analysis

    Two parallel lines represent 95% CI. PBVC = percent brain volume change.
