【摘要】 目的探讨影像学对肋骨原发性骨肿瘤的诊断价值及临床应用的意义。材料与方法本组中１８例摄取正侧位平片，８例加摄斜位片，２例加体层摄影，２例行ＣＴ检查。结果１２例良性病变平片显示与肋骨长轴一致的囊性破坏者１０例，４例伴有砂粒状钙化，６例恶性肿瘤均显示边界清楚的溶骨性破坏，ＣＴ显示软组织肿块突人胸腔。结论分析本组病例，表明Ｘ线平片对肋骨肿瘤多数可判断良恶性，ＣＴ在显示肿瘤骨质破坏及软组织肿块与邻近组织的关系方面优于Ｘ线平片。更多还原

【Abstract】 Purpose To investigate the diagnosis value and clinical application of imaging in diagnosis rid primary bone tumor. Materials and Methods Normotopia and lateral plain film was taken in 18 cases, oblique film was performed in 8 cases,was taken in 2 cases,CT was performed in 2 cases. Results of the 12 benign cases, 10 cases showed cystic destruction paralleled to the long axis of rib,4 cases complicated sandy calcification. 6 malignant tumors showed clear boundary osteolytic destruction and there is soft tissue protruding to thoracic cavity on CT. Conclusion X- ray plain film can distinguish benign tumors from malignant tumors of rib in majority. CT has more Superiority in displaying tumor’s bone destruction and the relationship of soft tissues and adjacent tis sues than X - ray film.更多还原
