Ultrasonography can visualize major brachial plexus structures like roots, trunks, and cords. However, it cannot evaluate nerve roots within foramina or the epidural space.

Area of Science:

  • Medical Imaging
  • Neuroanatomy
  • Neurology

Background:

  • The brachial plexus is crucial for upper limb function.
  • Accurate visualization of the brachial plexus is vital for diagnosing neurological conditions.
  • Current imaging modalities have limitations in evaluating certain brachial plexus segments.

Purpose of the Study:

  • To assess the feasibility of using ultrasonography (US) for brachial plexus visualization.
  • To identify which components of the brachial plexus are visible with US.

Main Methods:

  • Five healthy volunteers participated in the study.
  • Ultrasonography was employed to image the brachial plexus.
  • The supraclavicular and infraclavicular regions were specifically examined.

Main Results:

  • Ultrasonography successfully identified the roots, trunks, and cords of the brachial plexus.
  • Visualization was achieved in both the supraclavicular and infraclavicular areas.
  • Nerve roots within the neural foramina and the epidural space were not visualized.

Conclusions:

  • Ultrasonography is a feasible method for visualizing key brachial plexus structures.
  • US can complement existing diagnostic tools for brachial plexopathy.
  • Further research may explore advanced US techniques for deeper plexus segments.
