- FIG 1.
ROI placement for ALPS index calculation. A, A color-coded FA map shows the distribution of projection fibers (blue along z-axis) and association fibers (green along y-axis) at the lateral ventricle level. Spherical ROIs with a 5-mm diameter were placed in the projection and association areas. B, A schematic illustration of the relationship between the principal fiber and perivascular spaces, with the perivascular space running parallel to the medullary vein and perpendicular to the projection and association fibers.
- FIG 2.
Violin and box plots of the MR imaging metrics compared between the MOGAD and healthy control groups. The asterisk indicates FDR-corrected P < .05; ns, indicates no significance.
- FIG 3.
Scatterplots are presented to show the correlations between clinical characteristics and MR imaging metrics. An asterisk indicates statistical significance at P < .05.
