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.

目的：比較骨肉瘤和尤文氏肉瘤患者的初始強化模式。
方法：在2013年6月至2014年7月期間診斷為骨肉瘤和尤文氏肉瘤的患者被納入研究。患者進行動態對比增強磁共振成像以確定初始強化時間和強化曲線。
結果：21例（90%）骨肉瘤中有19例顯示較早初始強化，同樣情況在尤文氏肉瘤中則有5例（25%）。
結論：基於動態分析顯示初始強化時間的比例差異，骨肉瘤的高血管供應較尤文氏肉瘤為多。
