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.
