【摘要】 目的：借鉴误诊病例的经验教训，提高骨肿瘤的ＣＴ诊断水平。材料与方法：回顾性分析６５例经手术病理证实ＣＴ误诊的骨肿瘤或瘤样病变。结果：ＣＴ误诊的原因：（１）检查方法不当；（２）缺乏扎实的基础知识；（３）缺乏经验或对较少见骨肿瘤缺乏认识；（４）忽视对有诊断价值的ＣＴ征象认识；（５）ＣＴ的限度；（６）忽视局部骨肿瘤与周身性疾病或其他疾病的联系。结论：ＣＴ是诊断骨肿瘤或瘤样病变的重要手段，但有一定限度；学习掌握本专业及其相关的知识和技能、遵循正确的诊断思维方法、积累诊断经验是减少ＣＴ误诊的关键更多还原

【Abstract】 Objective: This analysis was to improve the CT diagnosis of bone tumors or tumorlike lesion of bone drawing lesions from 65 misdiagnosed cases.Materials and Methods:We made a retrospective analysis of 65 missed cases in CT diagnosis, which had been confirmed by pathology after surgery.Results:We found the following factors causing CT misdiagnosis: (1) improper procedure of examination; (2)lack of solid basic knowledge; (3)inexperienced or unfamilial with unusual or rare cases; (4)the ignored CT findings with diagnostic value; (5)the limits of CT; (6)the neglect of the relationship between local lesion and general conditions or other lesions.Conclusion: CT is an important means to diagnose the bone tumors or tumorlike lesions of bone, but it has some limits. To reduce the CT misdiagnosis, it is essential to master the speciality and the related knowledge and techniques, follow the correct procedure of diagnosis and accumulate the diagnostic experiences.更多还原
