【文章內(nèi)容簡介】 gn unless metastatic in origin n 邊緣光滑見于良性 (li225。nɡ x236。nɡ)結(jié)節(jié)，除外轉(zhuǎn)移瘤第十四 頁 ，共三十一 頁 。Air Bronchogram sign空氣 (kōngq236。)支氣管征n Recent studies have showed that an air bronchogram is more monly seen in malignant pulmonary nodules.It is most monly seen in BAC (bronchoalveolar cell carcinoma) and adenocarcinoma.n 最近一項研究表明，在惡性結(jié)節(jié)中經(jīng)常看見(k224。n ji224。n)空氣支氣管征，主要見于支氣管肺泡癌或腺癌第十五 頁 ，共三十一 頁 。n The case on the left shows an airbronchogram seen as a linear lucency (broad arrow) and as a more cystic lucency (small arrow) due to the fact that the bronchus is seen en face.第十六 頁 ，共三十一 頁 。n On the left two solitary pulmonary nodules.Based upon the morphology, which lesion has the most malignant features? n 下列兩個結(jié)節(jié)有哪些惡性 (232。 x236。ng)特征呢第十七 頁 ，共三十一 頁 。n The lesion on the far left has a spicuated margin and has lucencies within it.
