Abstract

Fifty-two patients with cerebrovascular risk factors without neurological abnormalities were examined by magnetic resonance imaging and were evaluated for their periventricular hyperintensity (PVH) on T2-weighted images. We assumed that PVH was not a mere focal finding of the brain but a kind of marker for condition related to arteriosclerosis and cerebral ischemia, and we tried to devise a model screening test, using common parameters available in most ordinary hospitals, to predict PVH. Multiple regression analysis was performed by setting up the PVH% (the volume percentage of PVH to cranial cavity) as a dependent variable and twenty-seven variables associated with general medical examination and brain atrophy as explanatory variables. We found that arteriosclerotic changes in the body as well as brain atrophy were significantly correlated with PVH, and that PVH could be predicted with a high contribution ratio of 0.70. It is clinically important to examine the elderly with our screening test to predict PVH in order to detect the early stages of ischemia.
