Patients tell us all the time “Doc, I hope you know what you’re looking at because that doesn’t look like anything to me!” Well, a photograph doesn’t do it justice, but here is one thing that an inexpensive ultrasound offers you that an MRI does not: the ability to see abnormal blood flow, most commonly neovascularization, in the setting of a tendonopathy. This is an example of peroneus longus tendonopathy causing pain and swelling over the lateral ankle in a runner. You just can’t get this information with an MRI, and in my experience, when neovascularization is present in a symptomatic tendon, you can expect a more difficult recovery, often necessitating more innovative treatment options to overcome the condition.
