Abstract	We used 3D texture analysis approach to examine the structural brain asymmetry. The method is based on extended, multi-sort cooccurrence matrices that employ intensity, gradient and anisotropy image features in a uniform way. The asymmetry in normals and in patients with pathological findings was evaluated on a large sample of 310 MRI-TI images with the focus on the asymmetry differences associated with gender. The analysis revealed higher asymmetry in males comparing females (t = 7.23, p < 10/sup -6/ in young and t = 2.65, p = 0.012 in elderly subjects). Separate analysis of white and gray matters showed significant asymmetry increase with age (F = 21.43, p < 10/sup -6/) of gray but not white matter.
