- A: Magnetic Resonance Imaging, or MRI, scans can show nerve damage, according to WebMD. An MRI of the spine can show damage to the spinal cord and associated nerves caused by both injury and disease. An MRI provides detailed images of soft tissues in the body, including the nervous system. Continue Reading

Diagnosing ALS MRI An MRI is a painless, non-invasive procedure that offers a very detailed picture of the spinal cord, the nerves that come out of the spinal cord, and the bones and connective tissues that surround and protect the spinal cord. It shows more detail than a CAT (computed axial tomography) scan or X-rays.

- If your doctor suspects a pinched nerve, you may undergo some tests. These tests may include: Nerve conduction study. This test measures electrical nerve impulses and functioning in your muscles and nerves through electrodes placed on your skin.

It can image every type of body structure at once, including bone, blood vessels and soft tissue.

- Spinal Diagnostics: Electromyography (EMG) Electromyography measures the electrical impulses of the muscles at rest and when contracted. Electromyography is usually done with nerve conduction studies. Nerve conduction studies measure how well individual nerves transmit electrical signals to the muscles.

EMG, Nerve Conduction Velocity, and SSEP These tests help to determine whether a specific symptom such as pain or weakness is the result of disorders of the muscles or nerves. The three most common electrodiagnostic studies are electromyography (EMG), nerve conduction velocity studies (NCVs), and somatosensory evoked potential studies (SSEPs). Electromyography (EMG) and nerve conduction studies (NCV's) are often done at the same time.

- Some of the more frequently ordered MRI types include: A Head MRI can look at the brain for tumors, an aneurysm, bleeding in the brain, nerve injury, and other problems, such as damage caused by a stroke. A head MRI can also find problems of the eyes and optic nerves, and the ears and auditory nerves.

Specialized Nerve Tests: EMG, NCV and SSEP Specialists analyze these signals to detect medical abnormalities in the spinal cord, nerves and the muscles that are connected to specific nerves. There are two types of EMG: intramuscular EMG and surface EMG. The intramuscular EMG is the most common.

- Why It's Done. MRI can detect a variety of conditions of the cervical spine as well as problems in the soft tissues within the spinal column, such as the spinal cord, nerves, and disks. This test is used to evaluate injuries of the seven cervical spine bones or spinal cord. Doctors also use it to:

- Diagnostic Testing. In order to fully determine the extent of the damage to the nerve, your doctor may order an EMG / NCV, an electrical conduction test to determine the passage of electrical currents through the nerves. These tests are sometimes done during actual surgery while the patient is sedated.

- Neuropathy is a serious condition. The SudoScan offers your doctor a way to measure the presence of neuropathy, and to track its progression. From that, he can come up with a treatment plan to help relieve your symptoms. Up until now, the most exact test for neuropathy was a nerve fiber biopsy. While usually tolerated well and safe for patients, biopsy does pose the possible risk of infection. That threat is non-existent with the SudoScan. This test is non-invasive, pain-free, and fast.

Magnetic Resonance Neurography Filler comments that these findings are comparable to the kinds of things nerve conduction tests may reveal. While MRN is good for showing the condition of peripheral nerves, a related technology, known as diffusion tensor imaging, reveals the inside of the brain and spinal cord. Generally, diffusion tensor imaging is studied right alongside MRN.

What is EMG and Nerve Conduction Study? When your muscles are sore or weak and you don’t know why, there are a couple of tests that can help give you answers. One is electromyography (EMG). The other is a nerve conduction study (NCS). They are often done at the same time. Your doctor can use the results of these tests to figure out whether you have a muscular problem or a nerve problem.

Center for Pain and Rehab Medicine Nerve Conduction Studies (NCS) During Nerve Conduction Studies, your EMG doctor will test different nerves to determine if they are conducting the body’s electrical activities normally. You will be connected to a computer (EMG machine) and the nerve being tested will receive very small electric shocks.

Radiculopathy (Pinched Nerve) To diagnose radiculopathy, your doctor will first perform a physical examination. They may then run certain tests or scans such as: an X-ray to view bone alignment or narrowing of the discs; an MRI scan to get images of soft tissue, your spinal cord, and nerve roots; a CT scan to see the fine details of your bones, including bone spurs

A Patient's Guide to Herniated Thoracic Disc Electromyography (EMG) can be used to diagnose diseases that damage muscle tissue, nerves or the points where nerve and muscle join. This test is useful in determining if there has been prolonged pressure on a nerve root. X-rays will not show a herniated disc.

Nerve Function Tests for Evaluating Low Back Problems - Topic Overview Muscle strength. Muscle strength tests can detect true muscle weakness, which is one sign of pressure on a nerve root. (Sometimes leg weakness is actually due to pain, not pressure on a nerve.) Most people who have herniated discs that cause symptoms also have some nerve root compression.

Peripheral Neuropathy If the doctor thinks you might have nerve damage, you may have tests that look at how well the nerves in your arms and legs are working. Nerve conduction studies check the speed with which nerves send messages. An EMG checks how your nerves and muscles work together.

Electromyography (EMG) NCV can determine nerve damage and destruction, and is often performed at the same time as EMG. Both procedures help to detect the presence, location, and extent of diseases that damage the nerves and muscles. Please see this procedure for additional information.

Diabetic Neuropathy: Your Diagnosis 7 Some doctors will lightly touch your toes with a finger (as you close your eyes or look away) to check for pressure sensation instead. 8 . Nerve Conduction Velocity and Electromyography Tests . Nerve conduction velocity (NCV) and electromyography (EMG) tests are sometimes used to help diagnose diabetic neuropathy.

Pinched Nerve If the pinched nerve is in the neck (cervical spine) or back (lumbar spine), an MRI or CT scan may be considered to make the diagnosis and look for the cause (bulging disc, arthritis, or fracture).hysical therapy is frequently beneficial when a pinched nerve is caused by problems in the neck or low back. Exercises may strengthen the back or core muscles and decrease or eliminate pressure on a nerve root.

Pinched Nerve Depending on the findings, the diagnosis may be made clinically or further testing may be required. Electromyography (EMG) is a nerve conduction study to help confirm the diagnosis of a pinched nerve and to determine the extent of nerve damage.
