摘　　要：脑胶质瘤是中枢神经系统常见肿瘤,因其生长具有高度侵袭性而常与正常脑组织分界不清,为临床准确诊断分级带来困难。弥散张量成像可微观监测水分子弥散运动并进行定性、定量分析从而反映脑组织微观结构的病理性变化、无创性显示脑白质纤维束。本文就弥散张量成像利用定量研究参数、脑白质纤维束显示等手段进行脑胶质瘤诊断分级的研究进展作一综述。Glioma is a common tumor of the central nervous system.Because of its highly invasive growth,It is often indistinguishable from normal brain tissue,which makes it difficult to make accurate diagnosis and grading in clinical practice.DTI can monitor the diffusion movement of water molecules microscopically and conduct qualitative and quantitative analysis to reflect the pathological changes of brain microstructure and display cerebral white matter fiber bundles noninvasively.This article reviews the research progress of DTI in the diagnosis and grading of glioma by quantitative research parameters and cerebral white matter fiber bundles display.
