Don’t do an MRI scan of the spine or brain for patients with only peripheral neuropathy (without signs or symptoms suggesting a brain or spine disorder).

Rationale and Comments

Because the vast majority of people with peripheral neuropathy (also called polyneuropathy) have the longest nerves of the body primarily affected (mostly in the toes and feet, but sometimes also in the hands), there is essentially no justification for MRI of the brain or spine in these cases.
