Abstract
Current medical treatments, including radiation therapy, chemotherapy, and hematopoietic growth factors, may affect the MR imaging appearance of bone marrow. A robust understanding of posttreatment marrow changes is required in order to differentiate these expected findings from pathologic marrow processes. Therapy-induced MR imaging characteristics are related to alterations in bone marrow cellular composition, vascularity, and metabolism. Therefore, posttreatment changes evolve in a time-dependent fashion and on occasion may be reversible. Therapy-specific complications such as radiation osteonecrosis and insufficiency fractures must also be differentiated and recognized by MR imaging.
