Lumbar puncture (LP): If peripheral neuropathy is the diagnosis, then a lumbar puncture wd prob be higher yield than an MRI. MRI only detects anatomical abnormalities. Peripheral neuropathy is caused by a systemic condition - infection, metabolic (diabetes), auto-immune, etc. It is a functional (not anatomic) problem. In the right context, a LP cd show evid 4 viral, MS, & other causes. MRI will likely yield nothing.
