This presentation reports a diffusion tensor imaging (DTI) study of white matter changes that may associate to the cerebrovascular disease, a risk factor of Alzheimers Disease (AD). Fractional anisotropy (FA) of the AD patients with and without T2 hyperintense lesions were obtained and compared. AD patients with cerebrovascular disease demonstrated statistically significant decreases in FA values in the right parietal, left frontal and right frontal regions, suggesting that the cerebrovascular disease is closely associated with DTI measured WM changes in AD.
