【摘要】 目的:评价肺部高分辨率CT(HRCT)对孤立性结节的定性诊断价值。方法:对46例孤立性结节的HRCT征象进行分析,观察病灶边缘、内部特征以及SPN的强化方式与良恶性的关系。结果:HRCT显示结节分叶征、毛刺或棘突以及结节完全强化更倾向于恶性结节诊断。钙化在良性结节中比例较高。结论:HRCT对肺部孤立性结节的诊断及鉴别有重要的意义。更多还原

【Abstract】 Objective: To evaluate High resolution CT (HRCT) in qualitative diagnosis of solitary pulmonary nodules(SPN). Methods: The HRCT appearances of 46 nodules were analysed. The relativity of noudles margin,internal structure and enhancement manner to benign or malignant were observed. Results: The lobulation,specula or whole enhancement manner of solitary pulmonary nodules on HRCT were found commonly in malignant noudles. Calcification proportion was high in benign SPN. Conclusion: HRCT is a valuable method in diagnosis and distinguishing diagnosis of solitary pulmonary nodules.更多还原
