Diffusion Tensor MR Imaging Tractography of the Pyramidal Tracts and Corpus Callosum in Children with Right-Sided Congenital Hemiparesis

Abstract

This study used diffusion tensor tractography to evaluate the diffusion parameters of the corpsus callosum and asymmetry in the diffusion parameters of the corticospinal tracts in children with congenital hemiparesis. Precision moving critically correlates with the integrity of the pyramidal tracts as evidenced in congenital hemiparesis by the correlation found between corticospinal lesions and motor deficits. Therefore we hypothesize that diffusion parameters correlate with the severity of hemiparesis measured using the Bayley Scales of Infant Development.
