ABSTRACT

Brachial plexus injury (BPI) is a severe neurologic injury that causes functional impairment of the affected upper limb. Imaging studies play an essential role in differentiating between preganglionic and postganglionic injuries, a distinction that is crucial for optimal treatment planning. Findings at magnetic resonance (MR) imaging help determine the location and severity of injuries. MR imaging demonstrates signal intensity changes in the spinal cord, enhancement of nerve roots and/or paraspinal muscles and the presence of root avulsion injuries. Diffusion-weighted neurography is a cutting-edge technique for visualizing postganglionic nerve roots, contrast material- nhanced MR imaging being recommended as additional studies. This study presents some classic MRI findings in patients with BPI, as well as a brief description of clinical applications of this imaging technique.
