WebWhite matter hyperintensities (WMHs) are clinically silent abnormalities visible in deep or periventricular white matter on CT or MRI. They are particularly apparent on FLAIR MRI, which is a T2-weighted sequence where the CSF signal is suppressed. What causes hyperintensity FLAIR signals? WebAt MRI, there is symmetric signal intensity abnormality in the pons, basal ganglia, midbrain, and subcortical white matter, with hypointensity on T1-weighted images and hyperintensity on T2-weighted/FLAIR images. Restricted diffusion is usually the earliest sign, seen in the lower pons within 24 hours of the onset of quadriplegia.
