An MRI may be able help identify structural lesions that may be pressing against the nerveso the problem can be corrected before permanent nerve damage occurs. Nerve damage can usually be diagnosed based on a neurological examination and can be correlated by MRI scan
Magnetic resonance imaging
Magnetic resonance imaging is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from CT or CAT scans and PET sca…
Can an MRI help diagnose nerve damage?
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. Nerve damage can usually be diagnosed based on a neurological examination and can be correlated by MRI scan findings. The MRI scan images are obtained with a magnetic field and radio waves.
Can a CT scan show nerve damage?

What nerves control movement?
Motor nerves, on the other hand, control voluntary movement and actions by communicating to muscles from the brain and spinal cord.
