MR imaging of plantar fasciitis: edema, tears, and occult marrow abnormalities correlated with outcome.

Abstract

We found signs on MR imaging that, to our knowledge, have not been described in the scientific literature for patients with plantar fasciitis. These signs included occult marrow edema and fascial tears. Patients with these manifestations seemed to respond to treatment in a manner similar to that of patients in whom MR imaging revealed more benign findings.
