Figure 2. Brain perfusion positive correlation with the number of optic neuritis attacks in RNMO patients.

The same slices as shown in Figure 1, presenting the perfusion positive correlation statistical parametric map, which was found in an extensive brain area mainly located in the white matter. Note that perfusion changes included periventricular areas. Statistical parametric map was thresholded at p value <0.01 (p value <0.05 corrected for multiple comparisons at the cluster level).
