Emergent musculoskeletal magnetic resonance imaging

The role of emergent musculoskeletal magnetic resonance (MR) imaging has expanded in recent years and now includes assessment of the extent and severity of musculoskeletal infection, diagnosis of occult fractures, characterization of complex fractures, and identification of selected vascular and nerve injuries associated with hip, knee, and elbow fractures and dislocations. In the elite athlete, emergent MR assessment of musculoskeletal injury allows prompt recognition of the nature of the injury, informed decision-making regarding the need for modification of competitive activity, and early institution of therapy. When surgical intervention is required, MR imaging facilitates preoperative planning.
