Post-therapeutic magnetic resonance imaging of bone tumors

Magnetic resonance imaging plays an important role in the therapeutic follow-up of patients with bone tumors. Follow-up includes monitoring of response to neoadjuvant chemotherapy prior to limb salvage surgery, assessment of local recurrence of tumor, differentiation of suspected recurrence from hematopoietic bone marrow reconversion, inflammation, seroma, or reactive tissue, and detection of therapeutic complications, such as osteonecrosis, infection, and radiation-induced sarcoma. This article reviews the role of magnetic resonance imaging in the therapeutic follow-up of patients with bone tumors.
