ABSTRACT
Objective To investigate the feasibility of hydrogen proton magnetic resonance spectroscopy (1 H-MRS)for detection of Wallerian degeneration of the pyramidal tract after cerebral infarction.Methods Multiple metabolic indices including NAA,Cho, Cr of the bilateral cerebral peduncle were detected by using 1 H-MRS in 1 5 patients with unilateral middle cerebral artery infarction and 1 5 age-matched healthy volunteers,NAA/Cr,Cho/Cr were also calculated.Comparing the difference between cerebral infarction group and the control group ,the ROC curve was analyzed.Results The values of NAA/Cr in the ipsilateral cerebral peduncle of cerebral infarction patients were significantly lower than that of the contralateral,and there were significant differences between the two groups(P 0.05),the Cho/Cr values of the ipsilateral and the contralateral cerebral peduncle had no significant difference compared with the control group (P >0.05).Conclusion 1 H-MRS can detect Wallerian degeneration of the pyramidal tract after cerebral infarction.
