What is MRI Brachial Plexus

An MRI (Magnetic Resonance Imaging) of the Brachial Plexus is a non-invasive and highly sophisticated diagnostic test. The Brachial Plexus is a complex network of nerves that originate from the neck region and control the chest, shoulder, arm, and hand movements. This procedure helps in capturing detailed images of these nerves.

• Use: It helps to detect a variety of conditions and abnormalities like injury, inflammation, tumors, and other disorders of the nerves.
• Procedure: During the test, the patient lies down on a sliding table and slides into a large tube-like machine where magnetic fields and radio waves are applied to create detailed images of the body. The procedure is painless but may induce a feeling of claustrophobia in some patients.
• Preparation: Patients are generally advised to wear comfortable clothes and remove any kind of metal objects including jewelry, glasses, dentures, etc. since the magnetic field of the MRI machine can attract metal.
• Duration: The procedure usually takes around 45 minutes to an hour. However, it can extend up to two hours based on the requirement.
• Interpretation: A radiologist interprets the images produced during the scan. The results can then be used to plan further treatment or surgery if necessary.

In conclusion, an MRI of the Brachial Plexus is a highly effective tool in diagnosing various conditions relating to the nerves originating from the neck region. It is a safe procedure with no known side effects or risks and provides highly detailed images that can help in the diagnosis and treatment of various nerve-related conditions.

• MRI Brachial Plexus is required when there is a suspicion of any abnormality or injury in the nerves of the brachial plexus. The brachial plexus is a network of nerves that sends signals from your spinal cord to your shoulder, arm, and hand. An injury here can cause numbness, weakness, and pain in these areas.
• This type of MRI scan is also required when the patient exhibits symptoms such as unexplained pain in the arm, shoulder or neck, lack of muscle control in the arm or hand, or a lack of feeling or sensation in the arm or hand.
• Further, MRI Brachial Plexus is used for the evaluation of various conditions such as brachial plexus injury, tumors or cancer that may be pressing on the brachial plexus, inflammatory conditions, and other diseases that affect the peripheral nerves.

• Individuals who have experienced a severe injury, such as a traffic accident or a fall, which has resulted in trauma to the neck and shoulder region may require a MRI Brachial Plexus. This is especially true if they are experiencing symptoms such as pain, numbness, or weakness in the arm, shoulder, or hand.
• Patients who have been diagnosed with a tumor or cancer in the neck or chest area may also require this scan. The MRI can help determine if the tumor or cancer is affecting the nerves of the brachial plexus.
• Individuals with certain inflammatory conditions, such as neurofibromatosis, that can affect the peripheral nerves may also need this type of scan. Lastly, it may also be necessary for individuals with unexplained chronic pain in the neck, shoulder, or arm.

• The MRI Brachial Plexus measures the structure and integrity of the brachial plexus nerves. It can provide details about the size, position, and path of these nerves.
• This type of MRI can also measure any changes or abnormalities in the nerves, such as swelling, lesions, tears, or other forms of damage.
• It can also measure the presence and size of any tumors or growths that may be pressing on the brachial plexus. Additionally, it can evaluate the severity of any inflammation or other diseases affecting the peripheral nerves.

• MRI Brachial Plexus is a non-invasive imaging technique that utilizes a strong magnetic field and radio waves to create detailed images of the brachial plexus, a network of nerves that originate from the neck region and branch out to control the shoulder, arm, and hand.
• The procedure does not require the use of ionizing radiation, which makes it a safer alternative to traditional X-rays and CT scans. Instead, it uses a magnet and radio waves to generate images.
• The patient is placed inside a large cylindrical machine where a magnetic field aligns the protons in the body. Then, a radiofrequency current is briefly turned on, causing these protons to produce a rotating signal that is detected by the machine.
• These signals are then processed by a computer to produce a detailed image of the brachial plexus which can be used to diagnose various conditions like injuries, tumors, and other abnormalities.

• Before the MRI, you should inform your doctor if you have any implanted devices or metal in your body, as this can interfere with the magnetic field of the MRI machine.
• You may be asked to fast for several hours before the test. You should also avoid consuming any caffeinated or alcoholic beverages.
• Wear comfortable, loose-fitting clothing. You may need to remove all jewelry and piercings and you may be asked to wear a hospital gown during the procedure.
• If you have a fear of enclosed spaces or anxiety, inform your doctor. They can provide you with mild sedative to ease your discomfort.
• It is important to arrive early for your appointment to complete any necessary paperwork and discuss the procedure with your healthcare provider.

• During the MRI, you will be asked to lie down on a narrow table that slides into the center of the MRI machine.
• A radiologist will monitor the process from a separate room. You will be able to communicate with them through an intercom.
• The machine will create a strong magnetic field around you, and then radio waves will be directed at your body. You won't feel anything during this part of the procedure.
• The MRI machine will make loud buzzing and clicking noises. You may be given headphones or earplugs to help with the noise.
• It's important to stay very still during the test, as movement can blur the images. The test can take anywhere from 30 minutes to 2 hours, depending on the specific details of the procedure.

The brachial plexus is a complex network of nerves that controls movement and sensation in the arm and hand. The normal range for a Magnetic Resonance Imaging (MRI) of the brachial plexus refers to the typical appearance and absence of any abnormalities or lesions in these nerves. This can vary slightly depending on the MRI technology used and the individual's unique anatomy. However, a normal MRI of the brachial plexus generally entails:

• No evidence of nerve root avulsion or displacement.
• No swelling or enlargement of nerves.
• No presence of tumors or other abnormal masses.
• Absence of any inflammation or fluid accumulation around the nerves.
• No abnormal signal intensity within the nerves.

Abnormal MRI findings of the brachial plexus can be due to various conditions or factors that affect the nerves. These can include:

• Traumatic injuries, such as shoulder dislocations or fractures, that can damage the nerves.
• Neuropathies, which are disorders that cause nerve damage or dysfunction.
• Tumors or growths that press on or invade the nerves.
• Inflammatory conditions, like neuritis, that cause swelling and inflammation of the nerves.
• Certain infections that can cause nerve damage.

Maintaining a normal MRI brachial plexus range involves taking steps to protect and care for your nerve health. This can include:

• Avoiding activities or movements that put excessive strain on your shoulder or arm.
• Practicing good posture to avoid nerve compression or strain.
• Regular physical activity to promote good circulation and nerve health.
• Eating a balanced diet rich in vitamins and nutrients that support nerve function.
• Seeking prompt medical attention for any shoulder or arm injuries.

After undergoing an MRI of the brachial plexus, it's important to follow certain precautions and aftercare tips to ensure a successful recovery and accurate results. This can include:

• Avoiding strenuous activity or heavy lifting for a period of time as advised by your doctor.
• Following any prescribed treatment or rehabilitation plan if an abnormality was detected.
• Monitoring for any changes in arm or hand sensation or function and reporting these to your doctor.
• Keeping any follow-up appointments for further testing or treatment as necessary.
• Drinking plenty of water to help flush out any contrast dye used during the MRI.
