Abstract: Objective To investigate the value of diffusion tensor tractography (DTT) quantitative assessment of corticospinal tract (CST) damage in acute intracerebral hemorrhage (ICH). Methods Thirty-two patients were enrolled in this study. DTT was obtained in early stage of ICH. The CST was reconstructed with Volume One 1.64 and diffusion Tensor Visualizer (dTV) software from Tokyo University. The compression, the displacement, the destruction, and the relative remaining number of the CST were calculated. Results The compression, the displacement and the destruction of the CST were observed in DTT images in all patients. The correlation coefficient between remaining number of the CST and score of Fugl-Meyer after the onset of ICH was 0.75 (P＜0.01). Conclusion DTT can quantitatively evaluate the state of CST injury in acute ICH.
