[Abstract] 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 (P<0.01).Conclusion: Quantitative DTT of CST could be used to predict the motor function in ICH patients.
