WebWhat is white matter flair hyperintensities? Abstract. White matter hyperintensities (WMHs) are brain white matter lesions that are hyperintense on fluid attenuated inversion recovery (FLAIR) magnetic resonance imaging (MRI) scans. Larger WMH volumes have been associated with Alzheimer’s disease (AD) and with cognitive decline. WebMRI indicates a few scattered foci of T2/FLAIR hyper-intensities. MRI indicates a few scattered foci of T2/FLAIR hyperintensities in the pons, periventricular and subcortical white matter. While these findings are non specific they are commonly seen with chronic microvascular ischemic change.
