Diffusion tensor imaging (DTI) is a recent technique that utilizes diffusion of water molecules to make assumptions about white matter tract architecture of the brain. Early on, neurosurgeons recognized its potential value in neurosurgical planning, as it is the only technique that offers the possibility for in vivo visualization of white matter tracts. In this review we give an overview of the current advances made with this technique in neurosurgical practice. The effect of brain shift and the limitations of the technique are highlighted, followed by a comprehensive discussion on its objective value. Although there are many limitations and pitfalls associated with this technique, DTI can provide valuable additional diagnostic information to the neurosurgeon. We conclude that current evidence supports a role for DTI in the multimodal navigation during tumor surgery.
扩散张量成像（DTI）是一种利用水分子扩散来推断大脑白质纤维束结构的最新技术。早期，神经外科医生就认识到它在神经外科手术规划中的潜在价值，因为它是唯一能够在体内可视化白质纤维束的技术。在这篇综述中，我们概述了该技术在神经外科实践中的当前进展。强调了脑移位的影响和该技术的局限性，随后对其客观价值进行了全面讨论。尽管该技术存在许多局限性和缺陷，但DTI可以为神经外科医生提供有价值的额外诊断信息。我们得出结论，目前的证据支持DTI在肿瘤手术的多模态导航中发挥作用。
