Three-dimensional MR imaging of the brachial plexus

Area of Science:

• Radiology and Imaging Science
• Neurology
• Medical Imaging

Background:

• Pathologic conditions of the brachial plexus (BP) can lead to severe, disabling complications.
• Traditional assessment methods may not fully capture the complexity of BP anatomy and pathology.
• Technological advancements in Magnetic Resonance Imaging (MRI) offer enhanced diagnostic capabilities.

Purpose of the Study:

• To describe MRI techniques for evaluating brachial plexus pathology.
• To explain differences and similarities in MRI sequences and protocols across vendors.
• To discuss key imaging findings, differential diagnoses, and management relevance for BP lesions.

Main Methods:

• Detailed description of MRI techniques for brachial plexus evaluation at 1.5 T and 3 T.
• Comparison of MRI sequences and protocols from different equipment vendors.
• Illustration of characteristic imaging findings for various brachial plexus pathologies.

Main Results:

• New MRI sequences and coils greatly facilitate the understanding and assessment of brachial plexus anatomy and pathology.
• Improved assessment of brachial plexus lesions leads to enhanced patient care.
• Identification of key imaging findings and pitfalls aids in accurate diagnosis and management.

Conclusions:

• Advanced MRI techniques are crucial for accurate diagnosis and management of brachial plexus conditions.
• Understanding vendor-specific protocols and potential pitfalls optimizes diagnostic yield.
• Improved imaging directly translates to better patient outcomes for brachial plexus injuries.
