Nerve fibers make up nerves, which are complex structures inside the brain. Magnetic resonance imaging of nerve fibers is a method for diagnosing neurological diseases in which nerve fibers are damaged.

Diffusion-weighted magnetic resonance imaging, also known as nerve fiber imaging, is a modern diagnostic imaging technique used to detect neurological diseases in which nerve axons are damaged.

Magnetic resonance imaging is an advanced diagnostic imaging technique used in the diagnosis of neurological diseases when the doctor suspects axonal damage or needs to find the relationship between the damage and the axon to avoid axonal damage when intervening in the damage.
