基于扩散张量的脑白质内神经纤维束的可视化技术

Visualization of Neuronal Fiber Tracts in White Matter Based on Diffusion Tensor

介绍了在功能磁共振成像的研究中发展非常快的扩散张量成像技术的基本原理,以及如何利用扩散张量数据来重建脑白质内的神经纤维束图像。其中主要介绍了白质束成像技术及其优缺点,并且分析了神经纤维束可视化技术的应用前景及其局限性。

In this paper, the basic principal or rational of diffusion tensor imaging （DTI）, which develops rapidly in the field of functional magnetic resonance imaging study, is introduced. And how to reconstruct the imaging of neuronal fiber tracts in white matter with the data of DTI is described. The technique of tractography, its advantages and disadvantages are analyzed. Finally, the limitations and further applications of neuronal fiber tracts visualization are discussed.
