Three lesion categories were analyzed: typical MS lesions (MSL), non-specific lesions in MS (nsWML-MS), and non-specific lesions in stroke (nsWML-S). SyMRI-derived parameters (R1, R2, proton density, and myelin content) were extracted from each region of interest (ROI), and one ROI was placed in NAWM per patient. Group differences were evaluated using non-parametric tests. Logistic regression models, both unadjusted and age-adjusted, assessed predictors of MS diagnosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Typical MS lesions showed lower myelin content and R1 and higher proton density than nsWML-MS (all\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.0001). Compared with nsWML-S, nsWML-MS demonstrated lower myelin content and higher proton density (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05), while R1 and R2 values did not differ. NAWM differences between MS and stroke emerged only after age adjustment. Age alone discriminated MS from stroke (AUC 0.83), with modest improvement when NAWM measures were added (AUC 0.86).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>SyMRI captures both lesion-specific and diffuse NAWM differences between MS and stroke.
