Can an MRI show a brachial plexus injury?
We found that MRI had high diagnostic performance in brachial plexus injury and the subgroup analysis with better sensitivity and accuracy in adult cases. In this study, MRI sensitivity and specificity in root avulsion in obstetric brachial plexus injury were 63% and 89%, respectively.
How is brachial plexus injury diagnosed?
Magnetic resonance imaging (MRI). It often can show the extent of the damage caused by a brachial plexus injury and can help assess the status of arteries that are important for the limb or for its reconstruction.

- X-ray.
- Electromyography (EMG).
- Nerve conduction studies.
- Magnetic resonance imaging (MRI).
- Computerized tomography (CT) myelography.
What can cause damage to the brachial plexus?
Several types of trauma — including motor vehicle accidents, motorcycle accidents, falls or bullet wounds — can result in brachial plexus injuries. Tumors and cancer treatments. Tumors can grow in or along the brachial plexus, or put pressure on the brachial plexus or spread to the nerves.

Where is the pain with brachial plexus injury?
