扩散张量成像（DTI）具有独特的能力，描绘轴突束内的白色物质，这是不可能与以前的非侵入性成像技术。在过去的10年中，我们已经看到了大量增加使用的DTI为基础的研究和评分的新的解剖知识和图像分析工具，近年来已经推出。这篇综述将概述基于DTI的研究和新的图像分析工具的最新进展。DTI为白色物质解剖学的表征提供了新的维度。这种对白色物质的表征可以大致分为两类。首先，基于逐像素的取向和各向异性信息，可以将白色物质包裹成组成白色物质束。其次，可以外推DTI信息以获得三维连接信息。基于DTI的这些功能，许多新的图像分析工具正在开发中，以调查白色物质的状态。在过去，白色物质常常被当作一个部分。利用弥散张量成像技术和近年来发展起来的分析工具，我们可以研究白色内结构的状态，加深我们对病理条件下白色结构及其异常的理解。
Diffusion tensor imaging (DTI) has a unique capability to delineate axonal tracts within the white matter, which has not been possible with previous noninvasive imaging techniques. In the past 10 years, we have witnessed a large increase in the use of DTI-based studies and a score of new anatomical knowledge and image analysis tools have been introduced in recent years. This review will provide an overview of the recent advancements in DTI-based studies and new image analysis tools. DTI provided new dimensions for the characterization of white matter anatomy. This characterization of the white matter can be roughly divided into two categories. First, the white matter can be parcellated into constituent white matter tracts, based on pixel-by-pixel orientation and anisotropy information. Second, the DTI information can be extrapolated to obtain three-dimensional connectivity information. Based on these capabilities of DTI, many new image analysis tools are being developed to investigate the status of the white matter. In the past, the white matter has often been treated as one compartment. With DTI and recently developed analysis tools, we can investigate the status of intra-white matter structures and deepen our understanding of white matter structures and their abnormalities under pathological conditions.
