Note.—All values are reported as the mean ± the standard deviation. Normal white matter was the centrum semiovale. NA indicates not applicable.
* This patient had a multifocal glioma.
† This patient had a low-grade glioma with a malignant core.
‡ T2-weighted EP images depicted abnormal signal intensity throughout the ipsilateral and contralateral centrum semiovale.
