Changes in the white matter of presumed vascular origin were first identified as hypoattenuation of the white matter on computed tomography but now are more often seen as patchy areas of signal hyperintensity in deep and periventricular white matter areas on T2-weighted sequences, particularly fluid-attenuated inversion recovery. For example, some studies have shown that those with T2 hyperintensities perform more poorly on certain tests of mental agility than those without.
