Magnetic resonance neurography (MRN) is the direct imaging of nerves in the body by optimizing selectivity for unique MRI water properties of nerves. It is a modification of magnetic resonance imaging. This technique yields a detailed image of a nerve from the resonance signal that arises from in the nerve itself rather than from surrounding ...
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve, though this may also refer to nerve root compression (by a herniated disc, for example).
An advancement of MRI that takes advantage of the tissue properties of nerves, called MR neurography (MRN), provides more detail. MR tractography (MRT) can also be of use in surgical planning as it can identify peripheral nerve abnormalities with a high correlation to intraoperative findings and has higher accuracy than MR neurography alone.

Pinched nerves arise when surrounding bone or tissue, such as cartilage, muscles or tendons, put pressure on the nerve and disrupt its function. [ 2 ] In a radiculopathy, the problem occurs at or near the root of the nerve, shortly after its exit from the spinal cord .
MRI has become the most frequently used study to diagnose spinal stenosis. The MRI uses electromagnetic signals to produce images of the spine. MRIs are helpful because they show more structures, including nerves, muscles, and ligaments than seen on X-rays or CT scans. MRIs are helpful in showing exactly what is causing spinal nerve compression.
It's used to describe an injury to nerves that have been compressed, constricted, or stretched in some way. It's often linked to pain in the neck or lower back. 5 Signs You Could Have a Pinched Nerve

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields , magnetic field gradients, and radio waves to form images of the organs in the body.
