摘　　要：目的:探讨不同病理类型骨肉瘤的X线、CT及MRI表现。方法:搜集经病理证实的23例骨肉瘤患者的影像学资料,其中23例均行X线检查,22例行CT检查,19例行MRI检查,分析其X线、CT及MRI表现。结果:23例中骨母细胞型骨肉瘤10例,均可见不同类型的瘤骨;纤维母细胞型骨肉瘤6例,以溶骨性破坏为主,部分病例见少量瘤骨;软骨母细胞型骨肉瘤5例,可见成簇分布的点状、环状的瘤骨,增强扫描呈环状/花边状/间隔强化;血管扩张型骨肉瘤1例;小圆细胞型骨肉瘤1例。结论:X线、CT及MRI对不同病理类型的骨肉瘤的诊断及鉴别诊断有一定作用。Objective：To investigate the X-ray,CT and MRI findings of different pathological subtypes of osteosarco-ma. Methods：23 （20 male, 3 female） patients with osteosarcoma confirmed by pathology were reviewed and the imaging manifestations were analyzed. All patients had X-ray plain films,22 had CT and 19 had MRI examinations. Results：Tumor bone were visible in 10 osteoblastic subtypes,oseolytic destructions with variable tumor bones were visible in 6 fibroblastic subtypes. Clustered dots or circular tumor bone with circular,lacelike or septal contrast enhancement were visible in 5 chon-droblastic subtypes. One case was vasodilation subtype and one case was small round cell subtype. Conclusion：Comprehen-sive imaging of X-ray,CT and MRI were helpful for differentiation of pathological subtypes of osteosarcoma.
