Therefore, the current diagnosis of PNS diseases is mainly dependent on clinical history, physical examination and electrophysiological examination of the data. Diffu- sion tensor imaging (DTI) is a method of image developed on the basis of diffusion weighted im- aging. It is used to image the anisotropy of water molecule motion, which can accurately show the microfluid structure. The quantitative data of fractional anisotropy (FA) and apparent diffusion coefficient (ADC) obtained by DTI technique can quantitatively evaluate the pathophysiological changes and structural features of nerve fiber bundles. DTI is often used in peripheral neurologi- cal disease research, the aim of the article was to review the DTI technology application in cranial nerve compression syndrome, lumbar disc herniation, tumor location and nerve injury repair.
