Diffusion tensor MR imaging is a technique that provides details on tIssue microstructure and organization well beyond the usual image resolution. With diffusion tensor MR imaging, diffusion anisotropy can be quantified and subtle white matter changes not normally seen on conventional MRI can be detected. The purpose of this article is to review the current applications of diffusion tensor MR imaging for the study of the brain, including normal aging, Alzheimer's disease, neuropsychiatric disorders, strokes, multiple sclerosis, brain tumors and intractable seizures.
扩散张量磁共振成像（Diffusion tensor MR imaging）是一种能够提供远超常规图像分辨率的组织微观结构和组织细节的技术。通过扩散张量磁共振成像，可以对扩散各向异性进行量化，并且能够检测到传统磁共振成像通常无法看到的细微白质变化。本文的目的是综述扩散张量磁共振成像在脑研究中的当前应用，包括正常衰老、阿尔茨海默病、神经精神疾病、中风、多发性硬化症、脑肿瘤和顽固性癫痫。
