MRI of the brachial plexus is used to provide a causal diagnosis for brachial plexopathies. It provides clear structural analysis of the brachial plexus, its intraneural integrity, as well as surrounding structures 1,3.

This section of the website will explain how to plan for an MRI brachial plexus scan, protocol for MRI brachial plexus, how to position and indications for MRI brachial plexus.
The brachial plexus is a complex neural network formed by lower cervical and upper thoracic ventral nerve roots which supplies motor and sensory innervation to the upper limb and pectoral girdle. It is located in the neck extending into the axilla posterior to the clavicle.
The brachial plexus (BP) provides sensory and motor innervation to the ipsilateral shoulder, chest, arm, and hand. Arising from the C5-T1 ventral rami of the spinal cord, the brachial plexus is divided anatomically into roots, trunks, divisions and cords (Figure 1).
MRI can be used in the setting of traumatic, compressive, or nontraumatic brachial plexopathy. In the setting of trauma, MRI is an alternative to CT myelography for assessment of preganglionic nerve root avulsions, with sensitivity and specificity of up to 93% and 72%, respectively (21, 22).
Magnetic resonance imaging (MRI) is the imaging modality of choice for the evaluation of the brachial plexus due to its superior soft tissue resolution and multiplanar capabilities. The evaluation of the brachial plexus however represents a diagnostic challenge for the clinician and the radiologist.
For magnetic resonance imaging (MRI) of non-traumatic brachial plexus (BP) lesions, sequences with contrast injection should be considered in the differentiation between tumors, infection, postoperative conditions, and post-radiation changes.
Magnetic resonance imaging (MRI) of the brachial plexus is the imaging modality of first choice for depicting anatomy and pathology of the brachial plexus. The anatomy of the roots, trunks, divisions and cords is very well depicted due to the inherent contrast differences between the nerves and the surrounding fat.
Knowledge of the key anatomic landmarks of the brachial plexus, as well as its normal and pathologic appearances at MRI, CT, and US, can help radiologists diagnose traumatic and nontraumatic brachial plexopathies.
Brachial plexopathy is a neurologic affliction that causes pain or functional impairment (or both) of the ipsilateral upper extremity. It may result from medical conditions and from violent stretching, penetrating wounds, or direct trauma.
