Radial organization of dysplastic cerebral cortices was hypothesized and magnetic resonance diffusion tensor imaging was performed for an infant who had a dysplasia in the right cerebral cortex. Absolute value of the inner product of the normal vector to the cerebral surface and the first eigen vector (that depicts the direction of the largest eigen value of diffusion tensor) was calculated for each pixel. The absolute value of the inner product was significantly larger for the dysplastic side than for the contralateral normal side of the brain.
