The prevalence and distribution of white-matter changes on different MRI pulse sequences in a post-stroke cohort.

No uniform criteria currently exist for rating white-matter (WM) high-signal foci on MRI. Ratings are based on descriptive terms, different pulse sequences and different WM areas. Reports on the prevalence and clinical correlates of high-signal foci have been contradictory.

Magnetic resonance imaging white matter hyperintensities and mechanism of ischemic stroke.

Background And Purpose: We sought to determine the relations between infarct subtype and white matter hyperintensities (WMHIs) on MRI.

Materials And Methods: We studied 395 ischemic stroke patients with 1. 0-T MRI.
