Can I run if MRI shows stress fracture but no pain?

In the last week alone I had telemedicine calls with two different runners with different types of stress fractures who asked what it means when they have no pain, but an MRI that "shows a stress fracture, but no crack in the bone."

It gets really confusing when it comes to classifying stress fractures based only on medical imaging like x-rays or MRI. 

If you wonder...

Can I run if my MRI shows a stress fracture, but I don't have any pain? 

That's what we're going to talk about today on the Doc On The Run podcast.
