Total bone marrow cells were flushed out from the femur and tibia of 5- to 8-week-old mice and treated with ACK buffer to remove erythrocytes. When interpreting opposed-phase marrow imaging, one must always consider the findings in the clinical context because any entity obliterating marrow fatsuch as fibrosis from a prior infection or inflammation, radiation-induced fibrosis, or marrow-replacement hematologic disorders, to name a fewcould have an appearance similar to that in this patient. Many variations in normal bone marrow signal and appearances are apparent and the reporting radiologist must differentiate these from other non-neoplastic, benign or neoplastic processes. High-signal T2 changes of the bone marrow in pediatric feet and ankle MRIs have a symmetric, fairly consistent pattern and disappear after the age of 15 years, leading us to believe that these high-Signal areas are normal and represent residual hematopoietic marrow.
