Research progress of diffusion tensor imaging in peripheral neuropathy

摘要

As an indispensable component of functional magnetic resonance imaging (fMRI), diffusion tensor imaging (DTI) is the unique noninvasive imaging method to visualize white matter fiber tracts in vivo. In addition, the diffusion data can be used for the determination of quantitative diffusion values such as isotropic and anisotropic diffusion that reflects condition of nerves. Recently, several studies have shown that DTI was useful for the evaluation of peripheral nerve. This paper gives an overview of the research progress on DTI application in peripheral neuropathy, including acute peripheral nerve injury, chronic peripheral nerve damage, peripheral nerve inflammatory lesions and peripheral nerve tumors.doi：10.3969/j.issn.1672-6731.2014.02.011.
