Objective: To compare the initial enhancement patterns in patients with osteosarcoma and Ewing sarcoma.
Methods: Patients diagnosed with osteosarcoma and Ewing sarcoma between June 2013 and July 2014 were included. Patients received dynamic contrast-enhanced magnetic resonance imaging scans in order to determine the initiation of enhancement time and the enhancement curve.
Results: In total, 19 of 21 (90%) patients with osteosarcoma showed earlier initiation of enhancement compared with five of 20 (25%) patients with Ewing sarcoma.
Conclusion: Patients with osteosarcoma showed more initial hypervascularity than did those with Ewing sarcoma, manifested by considerable differences in the percentage with early initiation of enhancement in the dynamic analysis.
