MRI新技术对骨骼系统肿瘤的诊断价值研究

目的探讨MRI(磁共振成像)动态增强新技术对骨骼系统良恶性肿瘤的诊断价值。方法随机选取45例骨骼系统恶性肿瘤患者作为试验组,另外选取42例骨骼系统良性肿瘤患者为对照组,均予以MRI动态增强新技术检查,比较两组在影像学上的差异性。结果良性骨骼系统肿瘤不强化比率、强化不均匀率、均匀强化率、骨骼系统肿瘤动态增强强化SI-Time曲线上升率、缓慢上升型率及平坦型率和恶性骨骼系统肿瘤相比差异均具有显著性(P<0.05)。结论 MRI动态增强能反映出骨骼系统肿瘤组织的血管化程度和血流灌注情况,可鉴别良恶性骨骼系统肿瘤。

Study on diagnostic value of MRI new technology for tumors of skeletal system

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 com- pared. Results The non-reinforcement ration, reinforcement nonuniformity ratio, uniform reinforcement ratio, escalat- ing 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.
