【摘要】 目的 探讨肺癌临床病理类型与肿瘤CT征象的关系。方法 回顾分析120例肺癌病理及CT征象,行统计学分析和卡方检验。结果 CT征象中,磨玻璃征发生率最高(24.17%),其次是空洞(14.17%),钙化发生率最低,仅为5.83%;腺癌磨玻璃征发生率(46.51%)远高于鳞癌(9.26%)和小细胞癌(17.39%),统计学差异显著(P<0.01)。肿瘤CT边缘征象,分叶和毛刺发生率最高,分别为65.83%、51.67%,其次胸膜凹陷征(31.67%)、血管集束征(20.83%);腺癌发生胸膜凹陷征明显高于其他2组(55.81%,24.07%,4.35%),有显著的统计学差异(P<0.01);腺癌分叶、毛刺以及血管集束征发生率较鳞癌和小细胞癌高。CT上腺癌磨玻璃征和胸膜凹陷征明显高于鳞癌和小细胞癌(P<0.01)。结论 肺癌的CT征象与临床病理类型密切相关。更多还原

【Abstract】 Objective To explore the relationship between the clinical pathological types and CT signs of lung cancer.Methods Pathological and CT findings of lung cancer in 120 cases were retrospectively analysed,and statistical analysis and Chi-square test were done.Results In CT findings of lung cancer,ground-glass opacity sign(GGO) was highest(24.17%),following cavitation(14.17%) and calcification(5.83%).GGO in adenocarcinoma(AC) was more than that in squamocellular carcinoma(SC) and small cell carcinoma(SCC)(P<0.01).Lobulate sign and speculation were highest presented(65.83% and 51.67%,respectively),following pleural indentation(PI) sign(31.67%) and vessel convergence sign(20.83%).Pleural indentation sign was more seen frequently in AC than SC and SCC(P<0.01) and the frequency of other edge signs of lung cancer in AC were higher than that in SC and SCC.GGO and PI were more frequently seen in AC than in SC and SCC(P<0.01).Conclusion CT signs of lung cancer is conducive to inference on pathological type of lung cancer.更多还原
