Correlation of corticospinal tract injury and the outcome of motor function after six months of intracerebral hemorrhage:quantitative evaluation with diffusion tensor tractography

Objective:To investigate the predicting value by analyzing corticospinal tract (CST) injury to the motor function after intracerebral hemorrhage (ICH) with quantitative diffusion tensor tractography (DTT).Materials and Methods:Diffusion tensor imaging was performed in twenty-five acute ICH patients,whose hemorrhage involves basal ganglia,internal capsule or corona radiate.The affected side of CST was reconstructed with Volume-One 1.64 and diffusion Tensor Visualizer II(dTV II) software from Tokyo University.The relative remaining number of CST,which is as quantitative indicator,was calculated.Fugl-Meyer scoring was used to evaluate the prognosis.Results:The correlation coefficient (r value) between relative remaining number of CST and Fugl-Meyer score after six month of ICH is 0.879 (P0.01).Conclusion:Quantitative DTT of CST could be used to predict the motor function in ICH patients.
