Magnetic resonance imaging in stress fractures: Making a correct diagnosis

Abstract

Stress fractures are fractures that occur due to a mismatch between bone strength and long-term mechanical stress. It is common to see magnetic resonance imaging (MRI) being used as first line of investigation for patients with bone pain. Lack of understanding of imaging appearances of a stress fracture can result in misinterpretation of bone marrow edema on MRI. We aim to stimulate readers’ thinking by illustrating MRI findings, in stress fractures and their possible differentials at various sites, with a view to reduce misinterpretation of MR scans and facilitate patient management.
