Today on the Doc On The Run Podcast, we’re talking about MRI versus CT scans for stress fractures and whether either one can actually tell you if it is safe to run.
If you’re a runner recovering from a stress fracture, one of the biggest questions is always the same:
“Can I run yet?”
Many runners assume there is some perfect imaging study that gives a simple yes or no answer.
But MRI scans and CT scans actually show very different things.
And understanding the difference can help you avoid wasting money, delaying recovery unnecessarily, or making bad decisions about training.
MRI scans are extremely useful early in the stress injury process.
They are very good at detecting inflammation inside the bone before there is even a visible crack.
That means MRI is often best for identifying stress reactions.
The MRI helps determine whether the bone is irritated and inflamed, even when X-rays still look normal.
CT scans use detailed X-ray imaging to evaluate bone structure.
That means CT scans are often better at identifying actual cracks in the bone.
If you already know there is a fracture line, CT scans may help determine whether new bone is forming across the fracture site.
That can sometimes make CT scans more useful later in recovery.
One of the biggest problems is that inflammation inside the bone can persist for a very long time.
Even when runners are improving and safely returning to training, MRI scans may still show inflammation.
That remodeling process can continue for months or even more than a year.
That means MRI findings alone do not necessarily tell you whether it is safe to run.
Medical imaging has to match your symptoms, your training progression, and your functional improvement.
No scan automatically gives you permission to run.
The goal is understanding whether the bone is actually tolerating stress and adapting appropriately.

If you are trying to decide whether you need an MRI, CT scan, or repeat imaging for a stress fracture, this episode will help you understand what those scans actually show and how runners should think about returning to training.
