AVN and alternate causes of BME have similar clinical presentations and often are referred to MR for evaluation. However, the appearance of these conditions can be nonspecific on non-contrast MR. The aim of this study was to determine the utility of dynamic-contrast enhanced MRI in cases of bone marrow edema for the differentiation of ischemia and hyperemia associated with bone marrow disease. DCEMRI was performed in 14 patients with bone marrow edema. T1, T2 and dynamic contrast characteristics were analyzed for each subject and correlated with clinical, imaging and/or surgical follow-up for the presence of AVN.
