| Abstract(in English) | It is known that brain tissues have age-related morphological changes through a set of statistical analysisusing large-scale brain MRI image databases. This fact allows us to estimate the age of a subject from brainMRI images by evaluating brain morphological changes with healthy aging. The age estimated from morphological changes of a human brain can be used for diagnostic support and early identification of brain disorders such as Alzheimer's Disease. This paper proposes an age estimation method using local features extracted from T1-weighted MRI images. Local features are defined by regional volume calculated from 1,024 local regions of GM, WM and CSF. We also add cortical thickness parcellated by Destrieux atlas tobrain local features in order to improve the accuracy ofage estimation. We evaluate performance of the proposed method using a large-scale dataset of healty Japanese. |
