Abstract(in English) It is well known that brain tissues have age-related morphological changes through a set of statistical analysis using large-scale brain MRI image databases. This fact allows us to estimate the age of a subject from brain MRI images by evaluating brain morphological changes with healthy aging. This paper proposes an age estimation method using local features extracted from T1-weighted MRI images. The brain local features are defined by volumes of brain tissues separated into 90 local regions denned by the Automated Anatomical Labeling atlas. We evaluate performance of the proposed method using 1,146 T1-weighted MRI images from the Aoba Brain Imaging Project and the Tsurugaya Project. We also analyze effectiveness of each local region for age estimation and discuss its medical implication.
