| Abstract(in English) | The detection of asymptomatic lacunar infarcts on MR images is important because their presence indicates an increased risk of severe cerebral infarction. Therefore, we developed computerized method for the detection of lacunar infarcts. However, false positives detected by our method are classified into four types which have different distributions in the feature space. Thus, it is difficult to distinguish between these specific types of false positives and lacunar infarcts by using a single classifier. In this study, we eliminated these false positives by use of the combining pattern classifier. The result indicated that the sensitivity for the detection of lacunar infarcts was 96.8% with 0.39 false positives per slice. Our computerized method would be a useful method for eliminating specific types of false positives. |
