What is a brachial plexus MRI scan?

A brachial plexus MRI scan is a specialised imaging test that produces detailed images of the network of nerves connecting the neck, shoulder, and arm.

This network, known as the brachial plexus, controls movement and sensation in the upper limb. The scan uses powerful magnets and radio waves to show the structure and condition of these nerves without using radiation.

It creates a series of detailed images that allow specialists to assess nerve alignment, surrounding tissues, and any abnormalities.

When might you need this type of scan?

This scan is recommended when there are symptoms affecting the nerves in the shoulder, arm, or hand, especially when the cause is not clear.

Unlike standard MRI scans, this one focuses specifically on the nerve network in this region, providing more targeted and detailed information.

What symptoms could lead to this scan?

You may be referred for a brachial plexus MRI if you experience:

Pain in the shoulder, arm, or hand
Weakness in the upper limb
Numbness or tingling sensations
Loss of movement or function

These symptoms often suggest possible nerve involvement that requires further investigation.

What conditions can a brachial plexus MRI help detect?

This scan can help identify a range of nerve-related conditions, including:

Nerve injuries following trauma (such as falls, sports injuries, or road accidents)
Brachial plexopathy causing weakness or loss of function
Tumours or growths affecting the nerves
Inflammation or infection of nerve tissue
Thoracic outlet syndrome (nerve compression between the neck and shoulder)
Post-surgical complications in the neck or shoulder
Radiation-related nerve damage following cancer treatment

It is particularly useful when symptoms do not have an obvious cause.

Who may be at higher risk of nerve-related shoulder and arm conditions?

You may be more likely to require this scan if you have:

A recent injury or trauma to the neck or shoulder
Ongoing nerve-related symptoms
Previous surgery in the shoulder or neck area
A history of cancer or radiation treatment
Conditions affecting nerve function

These factors may increase the need for detailed nerve imaging.

Why is early detection important?

Identifying nerve-related problems early can help prevent long-term complications. Without timely diagnosis, issues may lead to:

Persistent pain or discomfort
Reduced strength or mobility
Long-term nerve damage
Loss of function in the arm or hand

A brachial plexus MRI helps detect these problems early and supports appropriate treatment.

How does this scan support diagnosis?

A brachial plexus MRI provides detailed images that allow doctors to:

Examine the structure and alignment of nerves
Identify areas of damage, compression, or abnormality
Assess surrounding tissues and possible causes of symptoms

In some cases, a contrast dye may be used to improve visibility of the nerves and surrounding structures.

What happens after diagnosis?

Once the scan results are available, your doctor may recommend:

Further tests or specialist referral
Treatment for nerve injuries or underlying conditions
Physiotherapy or rehabilitation
Monitoring of existing conditions

The scan results help guide the most suitable treatment plan.

How should you prepare for your brachial plexus MRI scan?

Before your scan:

Remove all metal items such as jewellery, watches, or piercings
You may be asked to wear a hospital gown
Inform staff if you have implants or medical devices
Let the team know if you experience claustrophobia
Inform staff if you are pregnant or may be pregnant

In some cases, a contrast dye may be used to improve imaging clarity.

What happens during the scan?

You will lie on your back on the MRI table
Your head, neck, and shoulders will be carefully positioned
Cushions may be used for comfort and support
The machine produces loud tapping or humming sounds
You will be given earplugs or headphones
A call button is usually provided if you need assistance
Remaining still is essential for clear images

What happens after the scan?

You can return to normal activities straight away
If contrast dye was used, you may be monitored briefly
The scan is painless, although lying still may feel slightly uncomfortable
