【摘要】 目的回顾性分析81例肺内孤立性结节16层螺旋CT征象,对照组织病理类型,分析二者之间相关性。加深对肺内孤立性结节的认知。方法搜集有完整16层螺旋CT资料及病理证实81例肺内孤立性结节病例,对照分析良恶性结节不同CT征象之间差异,肺癌某些征象与分化程度之间关系。结果典型胸膜凹陷征是肺癌可靠征象;空泡征高度提示肺癌,且腺癌多于鳞癌;含气型肺、纵隔窗缩减率高度提示肺腺癌。血管集束征累及肺静脉者81.03%是肺癌,累及动脉者15.6%为恶性。肺癌最常见肿瘤与支气管关系为I型,次为Ⅳ型,V型最少见;良性结节最常见者为V型,次为I型。结论16层螺旋CT对肺内孤立性结节有很高诊断价值。肺癌的一些征象与组织类型与分化程度有一定相关性。更多还原

【Abstract】 Objective To analyze the relationship between 16-SCT signs of SPN and pathologic.Method 81 cases SPN which have the whole data of 16-SCT.All the nodules were conformed by pathologic.Different signs of malignant and benign and some signs between cancers and degree of polarization are analyzed.Results Typical sign of pleural indentation sign is a faithful sign to lung cancers.Vacuole signs mean lung cancer highly and more adencarcinomas were seen than squamous cancers.Lung-mediation reduction ratio of air type indicate squamous cancer strongly.81.3% vessel convergence that involved pulmonary veins were malignant contrast to 15.3%that involved the artery.Most common relationship of SPN-bronchus relationship are type I firstly and Ⅳ secondly,contrast to those benign are V and I type each.Conclusions 16-SCT does well in the diagnosis of SPN.There are some relationship between some sign of CT and pathologic and differentiate degree.更多还原
