Prevention of Stroke in Patients With Silent Cerebrovascular Disease: A Scientific Statement for Healthcare Professionals From the American Heart Association/American Stroke Association;Left, Silent brain infarct (arrow) on magnetic resonance imaging (MRI) fluid-attenuated inversion recovery (FLAIR) scan. ;A small (4-mm) subcortical silent brain infarct is visible as a hypodensity in the left thalamus on computed tomography (A). ;There is a 5-mm left thalamic hyperintensity (arrow) on the fluid-attenuated inversion recovery (FLAIR) sequence (left) with clear evidence of cavitation based on cerebrospinal fluid–like hyperintensity on T2-weighted (middle) and hypointensity on T1-weighted (right) images. ;Cortical silent brain infarct. ;White matter lesions of presumed vascular origin. ;Fazekas visual rating scale for magnetic resonance imaging white matter hyperintensities (WMHs). ;Distribution of magnetic resonance imaging (MRI) white matter hyperintensity by age category in the general population, measured with the Fazekas scale (Figure 6).
