Abstract

We have developed a computerized evaluation method of white matter hyperintensity (WMH) regions for the diagnosis of vascular dementia (VaD) based on magnetic resonance (MR) images, and implemented the proposed method as a graphical interface program. The WMH regions were segmented using either a region growing technique or a level set method, one of which was selected by using a support vector machine. We applied the proposed method to MR images acquired from 10 patients with a diagnosis of VaD. The mean similarity index between WMH regions determined by a manual method and the proposed method was 78.2±11.0%. The proposed method could effectively assist neuroradiologists in evaluating WMH regions.
