Traumatic injuries may demonstrate nerve discontinuity, neuroma formation, or T2 hyperintensity along the injury course. MRI and Advanced Neurography Techniques MRI brachial plexus imaging typically employs a combination of T1-weighted, T2-weighted, and STIR sequences to characterize lesions and inflammation.
Neoplastic Lesions of the Brachial Plexus: MRI Diagnostic Patterns and Clinical Insights
Inflammatory conditions like brachial neuritis often show diffuse nerve enhancement and subtle T2 changes, while neoplastic processes can present as nodular masses or diffuse nerve infiltration, necessitating careful differentiation from infectious or post-treatment changes. Primary Imaging Modalities and Their Applications Selection of the appropriate imaging technique hinges on the clinical question and suspected pathology.
The advent of MR neurography has been transformative, utilizing specific pulse sequences to highlight nerves with cerebrospinal fluid-like signal intensity. This allows for the detection of subtle nerve enlargement, signal changes indicative of injury, and the identification of neuromas or masses.

Diagnostic Patterns and Differential Diagnosis Interpreting brachial plexus imaging requires recognition of characteristic patterns associated with specific etiologies. Modern imaging modalities provide unprecedented insight, allowing clinicians to map the intricate architecture of nerves, arteries, and veins with exceptional clarity.
