摘　　要：DTI技术对于中枢神经系统疾病的诊断已被广泛应用,但是对周围神经的研究方兴未艾。研究表明,DTI可以识别早期周围神经的微观病变,可以对疾病进行早期诊治。相较于神经电生理检查、脊髓椎管造影等检查,DTI具有无创、定量评价的优势,有望成为新一代诊断周围神经系统疾病的辅助工具。本文从周围神经DTI值常用参数、感兴趣区域勾画方法、DTI值的测定方法、DTI值相关影响因素以及对周围神经显示的应用现状及其局限性等6个方面进行阐述。Diffusion tensor imaging (DTI) are applied to the diagnosis of the central nervous system diseases, while the study of DTI in clinical application of peripheral nervous system is in the ascendant. Former studies have shown that DTI can identify the early microscopic lesions of the peripheral nerves, therefore it is possible to diagnose and treat peripheral nerves diseases early. Compared with neurophysiological examination and spinal canal angiography, DTI has the advantages of noninvasive and quantitative evaluation. So it is expected to become a new generation of auxiliary tools for the diagnosis of peripheral nervous system diseases. In this paper, the common parameters of DTI value of peripheral nerve, delineation method of region of interest (ROI), calculation method of DTI value, influencing factors related to DTI value, application situation and limitations of DTI in peripheral nerve are discussed.
