What is the significance of mri findings of amount of fat surrounding exiting nerve roots of spine?
2 doctors weighed in across 2 answers
Foramen stenosis: There is normally fat surrounding the exiting nerve. When the nerve is pinched by a vertebral disc rupture, bone spur, or other mass, the amount of fat surrounding the nerve will appear decreased on the MRI scan. You can compare the amount of fat surrounding the nerve in question with the other nerves to get an idea of the amount of nerve compression.

Nerve fat: Each nerve has a ring of protective fat around it on MRI this seen as a bright signal so a ring of brightness around a nerve is normal and good to little fat around the nerve implies crowding or pressure contact of something other than fat like bone or disc. Ouch.
