WebIntroduction. A common finding in older adults is the presence of signal hyperintensities (SH) on magnetic resonance imaging (MRI). SH are areas of increased intensity appearing on T2-weighted images and are thought to reflect damage to the white matter and subcortical nuclei. WebWhite matter hyperintensities (WMH) are defined as areas with high signal intensities on T2-weighted MRI and as areas with low attenuation on CT. MRI has proved to be more sensitive than NCCT in detecting white matter hyperintensities.
