【摘要】 目的 :探讨肺炎性肿块与周围型肺癌的CT表现 ,提高对两者的鉴别诊断能力。方法 :回顾性分析 2 6例经病理或临床、CT随访证实的肺炎性肿块和 38例经病理证实的周围型肺癌的CT表现。将肿块按形态分为典型肿块与不典型肿块 ,并研究病变的CT征象 ,根据形态分类及CT征象的分析结果进行鉴别。结果 :肿块形态分类诊断肺炎性肿块的敏感度、特异度、准确度分别为 6 5 .4 %、 73.7%、 70 .3%。结合病变的CT征象综合分析后的敏感度、特异度、准确度分别为 80 .8%、86 .8%、82 .8%。结论 :根据肿块形态分类的初步结果 ,结合病变的CT征象的分析结果对肺炎性肿块与周围型肺癌的鉴别有重要价值。更多还原

【Abstract】 Objective:To investigate the CT manifestations of pulmonary inflammatory mass and peripheral lung carcinoma,and to improve the differentiation of the diseases.Methods:The CT manifestations of 26 cases of pulmonary inflammatory masses and 38 cases of peripheral lung carcinomas were retrospectively analyzed.All cases were proved by pathological or clinical appearances.The masses were divided into typical and atypical masses according to morphology.Studying the CT signs of lesions and combining them with the results of morphological classification improve diagnosis of the morphological classification.Results:According to the morphological classification of masses,the diagnostic sensitivity,specificity and accuracy of inflammatory mass were 65.4%,73.7% and 70.3% respectively.The improved sensitivity,specificity and accuracy were 80.8%,86.8% and 82.8% respectively.Conclusion:Combining the results of morphological classification of masses with the CT signs of lesions have important value in the differentiation of pulmonary inflammatory mass and peripheral lung carcinoma.更多还原
