Abstract (in Japanese) (See Japanese page) 
(in English) For the early detection of temporal lobe epilepsy and prognosis, the hippocampus is targeted in the diagnosis by positron emission tomography using fluorodeoxyglucose(FDG-PET). The PET image is superior to know the functional information, however, it is hard to distinguish small structures. One of the methods to analyze PET images structurally includes statistical analysis by the anatomical standardization. In this standardization, non-linear transformation is used to fit each brain structures to the template image. Due to the non-linear transformation, especially in the case of relatively small structures, there is a possibility that displacement errors occur.
In this study, after extracting the hippocampal region using a magnetic resonance imaging (MRI), MRI images and the PET images are registered using rigid transformation. We investigated the relationship between glucose metabolism and the subject’s age and sex. In addition, the result of the comparison of healthy group and epilepsy patients is described.
