Can you see nerve damage on a MRI?
MRI is sensitive to changes in cartilage and bone structure resulting from injury, disease, or aging. It can detect herniated discs, pinched nerves, spinal tumors, spinal cord compression, and fractures.
An MRI can be better at detecting abnormalities of the spinal cord, bulging discs, a small disc herniation, pinched nerves and other soft tissue problems. A CT scan is better than an MRI for imaging calcified tissues, like bones. CT scans produce excellent detail used to diagnose osteoarthritis and fractures.
- Pinched nerves usually are caused either a bony impingement, meaning there might be a joint that is pressing on the nerve, or in many cases by a bulging disc, herniated disc, or tight muscles. Chiropractic treatment can relieve pressure off the nerve and offer remarkable relief from pinched nerve pain.
- Muscle spasm in the back commonly accompanies pinched nerves and can be quite painful. Sometimes, nerves can be pinched and the only symptoms may be numbness and weakness in the arm or leg without pain. Other symptoms include tingling, burning, electric, and a hot/cold sensation.
- An MRI is often more helpful at diagnosing a pinched nerve. That's because an MRI can reveal the health of nerves and discs. An MRI or ultrasound (another noninvasive imaging test) can show the soft tissue in the shoulder and can determine whether the pain is being caused by injured ligaments or tendons.
With the myelogram , dye is injected into the spinal sac to outline the nerves and spinal sac so they show up clearly on the CT scan. A CT scan without dye is not as good at showing the discs and the nerves of the spine. The CT scan was developed before magnetic resonance imaging (MRI).
- For example, if you are in the emergency room and your doctor orders an MRI because he or she is worried about something going on in your brain, then the MRI will be visible to both the emergency room doctor and radiologist within minutes after it is done. Most MRIs are not done in an emergency situation.
- A computed tomography (CT) scan uses a special X-ray machine to take detailed pictures of organs and tissues inside the body. CT scans of the neck provide more details on neck injuries, tumors, and other diseases than other types of X-ray. CT can also show bone, soft tissues, and blood vessels in the same pictures.
- On the day of your MRI scan, you should be able to eat, drink and take any medication as usual, unless advised otherwise. In some cases, you may be asked not to eat or drink anything for up to four hours before the scan, and sometimes you may be asked to drink a fairly large amount of water beforehand.
electromyography (emg) EMGs can detect abnormal muscle electrical activity in many diseases and conditions. It is particularly useful in conditions such as muscle inflammation or myositis, pinched peripheral nerves like carpal tunnel syndrome, disc herniation with pinched nerves, ALS, and many more conditions.
- Over-the-Counter Treatments for Nerve Pain
- Topical painkillers. Many over-the-counter creams and ointments are sold to relieve nerve pain.
- Painkilling medicines. Some people with neuropathic pain turn to familiar over-the-counter painkillers like acetaminophen, aspirin, and ibuprofen.
- Supplements and vitamins.
- EMG measures the electrical activity of your muscle during rest, slight contraction, and forceful contraction. An abnormal EMG result may be a sign of a variety of muscle or nerve disorders, including: Polymyositis (an inflammatory muscle disease that causes decreased muscle power)
- Treatment options. Hot and/or cold therapy – Heat therapy helps to relax tense muscles and decrease muscle spasms, which some patients experience with a pinched nerve. Cold therapy, on the other hand, helps to reduce inflammation and pain.
