Diffusion tensor imaging is a variation of magnetic resonance imaging that measures the diffusion of water in tissues. This can help measure and quantify a tissue's orientation and structure, making it an ideal tool for examining cerebral white matter and neural fiber tracts. It is only beginning to be utilized in psychiatric research. This article reviews the theory behind diffusion tensor imaging, its potential to map fiber tracts in the brain, and its recent use in psychiatric research.
扩散张量成像（Diffusion tensor imaging）是磁共振成像的一种变体，用于测量组织中水分子的扩散。这有助于测量和量化组织的方向和结构，使其成为检查脑白质和神经纤维束的理想工具。它在精神病学研究中的应用才刚刚起步。本文回顾了扩散张量成像背后的理论、其在绘制脑内纤维束方面的潜力以及其在精神病学研究中的最新应用。
