Value of getting an MRI on both feet

There are only a few occasions when you might want to get an MRI on both feet. 
 
Truthfully, getting an insurance company to agree to pay for an MRI on both feet is not easy to do. 

A few years ago I helped a runner who was training for marathons when he got injured. He was super fit. But on a long, super steep run in Yosemite he did some damage to tendons in both of his feet.

He really needed an MRI on both feet. So, I wrote an order for his MRI's. But, when the MRI facility tried to get prioritization, the insurance company denied the MRI request.

That just didn't make any sense to me. 

Is it valuable to get an MRI on both feet?

That's what we're talking about today on the Doc On The Run Podcast.
