“…The detected cortical lesion load is comparable with the bulk of cortical lesions assessed by specialized MR imaging methods developed for sensitive cortical lesion delineation. 13,15,16,18,29 While it has been reported that cortical lesions are more conspicuous on 3D double inversion recovery compared with 3D-FLAIR images, 13,17 the former is not yet widely available on clinical scanners. FLAIR hyperintensities might represent lesions, perivenular spaces, or CSFrelated flow artifacts.…”
