X线、CT、核磁共振成像检查对骨肿瘤诊断价值比较

目的评价X线、CT、核磁共振成像（MRI）影像学检查方法对骨肿瘤的诊断价值。方法42例骨肿瘤患者均行X线检查，CT检查39例，MRI检查12例，并与手术病理结果相对照，比较三种影像学方法的诊断价值。结果42例中良性骨肿瘤11例（骨巨细胞瘤6例，骨软骨瘤5例），恶性骨肿瘤18例（骨肉瘤14例，软骨肉瘤4例），骨转移瘤13例。X线、CT和MRI诊断正确率分别为76．2％、92．3％和100．0％。结论三种影像学检查均可早期发现、早期诊断骨肿瘤，为临床提供可靠治疗依据。

Comparison the value of diagnostic in patients with bone tumors by three kinds of imaging

Objective To evaluation diagnosis value of bone tumors by X-ray,CT,magnetic resonance imaging(MRI) imaging methods.Methods 42 cases with bone tumor were detected by X-ray,39 cases and 12 cases were detected by CT and MRI,respectively.The clinical data in bone tumors by three imaging methods were comparied with the results of pathology.Results There were 11 cases with benign bone tumor(6 cases with giant cell tumor of bone and 5 cases with osteochoedroma),18 cases with malignant bone tumor( 14 cases with osteosarcoma,4with chondrosarcoma),13 with metastatic tumor.The accuracy diagnostic rates of X-ray,CT and MR were 76.2%,92.3% and 100.0%,respectively.Conclusion Three kinds imaging of bone tumors can be early explored,diagnosised and provided a reliable basis of clinical treatment.
