Magnetic resonance (MR) imaging clearly visualizes the brachial plexus. This multiplanar technique offers detailed anatomical views superior to other methods for nerve branch identification.

Area of Science:

  • Radiology
  • Neuroimaging
  • Anatomy

Background:

  • The brachial plexus is a complex network of nerves crucial for upper limb function.
  • Conventional imaging modalities have limitations in fully delineating brachial plexus anatomy.
  • Detailed visualization is essential for diagnosing and managing neurological conditions affecting the arm.

Purpose of the Study:

  • To evaluate the utility of multiplanar magnetic resonance (MR) imaging for visualizing normal brachial plexus anatomy.
  • To assess the ability of MR imaging to differentiate brachial plexus structures from surrounding tissues.
  • To compare the detailed anatomical information provided by MR imaging with other radiologic techniques.

Main Methods:

  • Magnetic resonance imaging (MRI) of the brachial plexus was performed in seven healthy volunteers.

  • Imaging was conducted in axial, coronal, and sagittal planes.
  • Normal anatomical structures were identified by comparing MR images with cadaver sections and gross dissections.

    • Main Results:

    • MR imaging effectively differentiated brachial plexus components from adjacent muscles and vascular structures.
    • Multiplanar imaging provided excellent delineation of the entire brachial plexus, from ventral rami to peripheral nerve branches.
    • The technique demonstrated superior anatomical detail compared to previous radiologic modalities.

    Conclusions:

    • Multiplanar MR imaging is a valuable tool for visualizing the normal brachial plexus.
    • This imaging approach offers detailed anatomical assessment, aiding in the diagnosis of brachial plexus pathologies.
    • MR imaging provides enhanced delineation of nerve structures, improving diagnostic accuracy.
