MRI scans can show how severe the nerve compression in the neck is. They will also allow doctors to see whether a herniated disk is causing compression of the nerve or the spinal cord.
Neck or low back pain that radiates into your arms or legs is often a sign of impingement or pinching of a nerve as it emerges from your spinal cord. An MRI may be able help identify structural lesions that may be pressing against the nerve so the problem can be corrected before permanent nerve damage occurs.
MRI scans which show soft tissues, such as nerves and discs, are generally preferred over CT scans which show bony elements. Advanced imaging can show exactly which nerve or nerves are being pinched and what is causing the nerve to be pinched.
Pinched nerve signs and symptoms include: Numbness or decreased sensation in the area supplied by the nerve. Sharp, aching or burning pain, which may radiate outward. Tingling, pins and needles sensations (paresthesia)
Ultrasound testing: Ultrasounds use sound waves to provide a detailed picture of soft tissues and bones. This type of testing is useful for diagnosing a variety of conditions, including pinched nerves.
The most frequently recommended treatment for a pinched nerve is rest for the affected area. Your doctor will ask you to stop any activities that cause or aggravate the compression. Depending on the location of the pinched nerve, you may need a splint, collar or brace to immobilize the area.
Extra sleep and rest
In many cases, resting the affected area and getting extra sleep is enough to allow the pinched nerve to heal on its own. While treating a pinched nerve, it is also important not to overuse the nerve. Nerve damage can be made worse by overuse.
This causes symptoms such as sharp pain in your neck, shoulder, arm, hand, or back. You may also have tingling or numbness. Sometimes it makes your arm weaker. The symptoms may get worse when you turn your head, cough, or sneeze.
Cervical radiculopathy, commonly called a "pinched nerve," occurs when a nerve in the neck is compressed or irritated where it branches away from the spinal cord. This may cause pain that radiates into the shoulder and/or arm, as well as muscle weakness and numbness.
If left untreated, it may lead to permanent nerve damage. The most common symptoms of a pinched nerve include neck pain that travels down the arms and shoulders, difficulty lifting things, headache, and muscle weakness and numbness or tingling in fingers or hands.
To determine whether you have a pinched nerve or something else, speak with a primary care doctor, neurologist or neurosurgeon. The doctor will ask you questions about your pain and medical history, and do a physical examination to determine if you have a pinched nerve or another issue.
MRI is an imaging method that is very sensitive in detecting inflammation and also bone erosions. This makes MRI an interesting tool to measure the course of the disease in randomised clinical trials and this suggests that MRI may also be useful in the diagnostic process.
A MRI in the neck may show any of the following conditions: Tumors in the bones or soft tissues of the cervical spine (neck) Herniated discs or bulging discs in the cervical spine. Aneurysm in the arteries of the cervical spine.
Pressure on the spinal cord in the cervical region can be a serious problem, because virtually all of the nerves to the rest of the body have to pass through the neck to reach their final destination (arms, chest, abdomen, legs). This can potentially compromise the function of many important organs.
Most often this type of exam is used to help diagnose the cause of symptoms in the neck, such as pain or stiffness. Your health care practitioner may request this scan if pain hasn't improved with basic treatment or if the pain is accompanied by numbness or weakness.
Some of the most common neck conditions that may require surgery include the following: A pinched nerve (cervical radiculopathy): With this condition, excess pressure is placed on one of the nerve roots in your neck.
Pinched Nerve Diagnosis
According to the American Academy of Orthopaedic Surgeons, a doctor may take an X-ray, a computed tomography (CT) scan, or a magnetic resonance imaging (MRI) scan to find the cause of the pinched nerve.
Can a Chiropractor Treat Pinched Nerve Pain? Yes, chiropractors provide a variety of safe, effective treatments for pinched nerve pain. Chiropractic care and decompression therapy may involve spinal manipulation to alleviate pressure from a herniated disc or bulging disc.
Why is a cervical MRI done? A cervical spine MRI is usually used to diagnose the cause of neck pain. It's often performed if the pain hasn't improved with basic treatment. It may also be done if the pain is accompanied by numbness or weakness.
A cervical spine MRI also can help doctors: Evaluate symptoms such as pain, numbness, tingling or weakness in the arms, shoulders, or neck area. Find some types of chronic diseases of the nervous system. Diagnose tumors, bleeding, swelling, infections, or inflammatory conditions in the vertebrae or surrounding tissues.
MRI is the better choice for imaging soft tissue but its disadvantages are long examination times and the necessity for patient compliance. For imaging the nervous system and salivary glands, MRI is more useful than CT unless infiltration of the bone or calcification in the gland is assumed.
Air and hard bone do not give an MRI signal so these areas appear black. Bone marrow, spinal fluid, blood and soft tissues vary in intensity from black to white, depending on the amount of fat and water present in each tissue and the machine settings used for the scan.
