Abstract:
Objective To investigate application of diffusion tensor tractography (DTT) on evaluating motor dysfunction degree of patients with cerebral infarction and explore the relationship between infracted focus and cortical spinal tract(CST).Methods Forty patients with cerebral infarctions in the different periods and 30 healthy volunteers were enrolled our study.They all underwent DTT check and then established CST.Meantime,all the patients were measured ADL score according to activities of daily living (ADL) on admission and two months after the onset.Results DTT image was made for both in patients and health control people.The CST was built in people in control group and its shape was like the adults'.Its shape was from the precentral gyrus down to internal capsule and continued to pontine and medulla oblongata.Each successive was form good consistency.The DTT image of patients' health side was like normal and injury corticospinal tract was affected by influence of infarction area at different level,manifested as loss of discontinuity and anatomical configuration consistency.Based on the degree of CST,there were 9 cases in grade Ⅰ,20 cases in grade Ⅱ and 11 cases at grade Ⅲ.DTT image showed that the damage level of CST had an negative relation with ADL score at 2 month after therapy (r =-0.914,P ＜ 0.05).Conclusion DTT can show the spatial positions of infarctions and CST at non-invasive lesion and analyze the influence of infarctions and corticospinal tract.Therefore,it can serve as the objective proof for judging the injury of the motor function and evaluating prognosis.
