Our neurologist said the MRI does not show enough detail to show nerve damage or inflammation. My wife has had three MRI's. They cost, due to an agreement between our PPO and the outfit, between $650 and $850 each, depending on whether they use a contrast medium when they do the scan. Call around and tell them your story, that your doctor has prescribed an MRI but you have no insurance, so how much will it be if you pay cash? My brother tore his ACL years ago when he had no insurance, and he found a place who did it for $500. Talk to the head cheese, not the knucklehead at the counter.
