摘　　要：胶质瘤为中枢神经系统常见恶性肿瘤,手术切除为治疗最有效治疗手段,而术前评估极为重要。基于弥散张量成像(DTI)的弥散张量纤维束成像(DTT)可无创显示活体内脑白质纤维束走行,定量评估胶质瘤病理分级、与白质纤维的解剖关系及瘤周白质纤维损伤程度。本文就高阶DTT评估胶质瘤研究进展进行综述。Glioma is a common malignant tumor of central nervous system,surgical resection is the most effective treatment,and preoperative evaluation of glioma is very important.Based on diffusion tensor imaging(DTI),diffusion tensor tractography(DTT)can noninvasively display the course of white matter fiber tracts in vivo,and quantitatively evaluate the pathological grade of glioma,the anatomical relationship with white matter fiber and the damage degree of white matter fiber around glioma.The research progresses of high-order DTT for evaluating glioma were reviewed in this article.
