[摘要] 目的 探討MRI（磁共振成像）動態增強新技術對骨骼系統良惡性腫瘤的診斷價值。 方法 隨機選取45例骨骼系統惡性腫瘤患者作為試驗組，另外選取42例骨骼系統良性腫瘤患者為對照組，均予以MRI動態增強新技術檢查，比較兩組在影像學上的差異性。結果 良性骨骼系統腫瘤不強化比率、強化不均勻率、均勻強化率、骨骼系統腫瘤動態增強強化SI-Time曲線上升率、緩慢上升型率及平坦型率和惡性骨骼系統腫瘤相比差異均具有顯著性（P<0.05）。結論 MRI動態增強能反映出骨骼系統腫瘤組織的血管化程度和血流灌注情況，可鑒別良惡性骨骼系統腫瘤。

[Abstract] Objective To observe the diagnostic value of MRI new technology for tumors of skeletal system. Methods Forty-five patients with malignant tumor in skeletal system were selected radomly as the experiment group， and 42 cases with benign tumour in skeletal system were selected randomly as the control group. Two groups received the examination of MRI new technology of dynamic enhancement. The difference for image between two groups was compared. Results The non-reinforcement ration， reinforcement nonuniformity ratio， uniform reinforcement ratio， escalating rate of dynamic enhancement reinforcement SI-Time curve， slowly rising ratio and flat rate were more evident of malignant tumor in skeletal system compared with that of benign tumour in skeletal system （P<0.05）. Conclusion MRI dynamic enhancement not only can reflect vascularization degree and blood perfusion of tumor tissue in skeletal system， but also can identify malignant and benign tumour of skeletal system.

骨腫瘤是臨床上常見的較難診斷的疾病之一，因其有易變性、復雜性和多樣性，使得其影像學表現呈現出多樣性。X線平片有良好的空間分辨率，能體現腫瘤形態特征變化，但是對于觀察軟骨、肌腱韌帶等診斷困難，而MRI則以能清晰顯示軟骨結構、可多平面成像、對骨髓異常十分敏感的優勢在骨骼系統腫瘤的診斷和鑒別上有重要作用[1]。本研究通過對MRI動態增強新技術對骨骼系統良惡性腫瘤影像學情況的探討，以期提高對骨骼系統腫瘤的診斷水平。
