A structured reporting system that includes the root, trunk, division, cord, and terminal branch level ensures comprehensive coverage and clear communication with the referring clinician regarding the status of the brachial plexus. Differential Diagnosis and Reporting When interpreting MRI studies, distinguishing between true pathological processes and technical artifacts is crucial.

These roots converge to form trunks, which subsequently divide into anterior and posterior divisions. Localization and Surgical Planning Detailed mapping of the brachial plexus anatomy is indispensable for surgical interventions, including nerve transfers and brachial plexus blocks.
Similarly, the interscalene brachial plexus is often surrounded by complex muscular anatomy that can create flow voids or signal heterogeneity, requiring careful evaluation to avoid misdiagnosis. Moreover, inflammatory conditions like brachial neuritis or tumor infiltration, such as that seen in Pancoast tumors, are readily identified through characteristic signal abnormalities within the brachial plexus anatomy.

MRI Sequences and Technical Considerations Standard T1-weighted sequences provide excellent anatomical contrast for fat-suppressed images, highlighting the nerve fascicles against the muscle background. T2-weighted sequences are particularly sensitive to nerve edema and pathology, increasing the visibility of inflammatory or traumatic changes.
