We review the current knowledge concerning clinical applications of the advanced technique of magnetic resonance imaging (MRI): diffusion tensor imaging (DTI) of the spinal cord. Due to technical difficulties, DTI has rarely been used in spinal cord diseases. However, in our opinion it is potentially a very useful method in diagnosis of the different pathological processes of the spinal cord and spinal canal. We discuss the physical principles and technical aspects of DTI, as well as current and future applications. DTI seems to be a very promising method for assessment of spinal cord trauma, spinal canal tumors, degenerative myelopathy, as well as demyelinating and infectious diseases of the spinal cord. DTI enables both qualitative and quantitative (by measuring of the fractional anisotropy and apparent diffusion coefficient parameters) assessment of the spinal cord. The particular applications are illustrated by the examples provided in this article.
我们回顾了磁共振成像（MRI）高级技术在临床应用方面的现有知识：脊髓的弥散张量成像（DTI）。由于技术困难，DTI 在脊髓疾病中很少使用。然而，我们认为它在诊断脊髓和椎管的不同病理过程方面具有潜在的非常有用的方法。我们讨论了 DTI 的物理原理和技术方面，以及当前和未来的应用。DTI 似乎是评估脊髓损伤、椎管肿瘤、退行性脊髓病以及脊髓脱髓鞘和感染性疾病的非常有前途的方法。DTI 能够对脊髓进行定性和定量（通过测量分数各向异性和表观扩散系数参数）评估。本文通过提供的示例说明了特定的应用。
