Statistical quantification of brain shape deformation with homologous brain shape modeling

摘要

Brain shape is deformed regionally by kinds of cerebral diseases and the degree of progress. Therefore quantitative evaluation of the deformation using MR images is effective for diagnosis of cerebral diseases. We proposed a homologous brain shape modeling deformation for quantitative evaluation of the brain shape using sulcal-distribution index (SDI) in MR images. So in this paper, we propose the homologous brain shape modeling. And we find the availability of the homologous brain shape modeling by investigating relationship between the movement distance with the homologous brain shape modeling and gray matter (GM) density of voxel based morphometry (VBM). This study employed nine male and two female and investigate a difference between male group and female group. The experimental results showed that the relationship between the homologous brain shape modeling and VBM was found from the same detection significant difference.
