T2 hyperintense foci in the subcortical white matter are widely recognized on neuroimaging as indicators of underlying brain tissue abnormalities, such as white matter lesions, small vessel disease, or demyelination.
The claim is specific and empirical, dealing with the radiological interpretation of T2 hyperintense foci. Multiple papers support the premise that T2 hyperintensities in the white matter signify underlying pathology, microstructural damage, or disease burden. There are no refuting papers.
