Abstract (in Japanese) (See Japanese page) 
(in English) Considerable number of intractable epilepsy patients are accompanied with cortical dysplasia. It is very effective to detect cortical dysplasia lesions in pediatric brain MR images when we plan treatment. However, there are few automated methods for detecting cortical dysplasia with MR images of pediatric brain. This paper proposes an estimation method of cortical dysplasia degree using support vector machine (SVM). To evaluate the cerebral cortex layer, the proposed method extracts features from intensity profiles between cerebral surface and white matter. And, we compare proposed method with conventional method. The experimental results for three subjects with cortical dysplasia showed that the proposed method detected cortical dysplasia lesions with a mean sensitivity of 90.9 %, a mean specificity of 93.1 %, and a mean efficiency of 92.0 %.
