摘要
目的：探讨肺鳞、腺癌的 ＭＲＩ信号及形态学表现。材料和方法：经病理证实的肺鳞、腺癌 １６例， ＭＲＩ可见肿块１４例，其中鳞癌８例，腺癌６例，比较二者之间的ＭＲＩ信号及形态学改变。结果：肺鳞癌ＭＲＩ Ｔ２ＷＩ多为坏死为主的不均匀稍高信号（４／８），肺腺癌ＭＲＩ Ｔ２ＷＩ多为纤维分隔为主的不均匀稍高信号（４／６），二者之间信号改变有统计学差异。Ｔ１Ｗ１二者之间无差异。肺鳞癌肿块＞５ｃｍ，分叶征及阻塞性改变比肺腺癌发生率高。结论：肺鳞、腺癌的 ＭＲＩ信号及形态学改变有一定鉴别价值。
Purpose: To evaluate the MR findings of lung squamous-cel carcinoma and adenocarcinoma. Materials and Methods: Sixteen cases of lung cancer proved pathologically were reported. Of 16 cases, 9 were squamous-cell carcinoma and 7 were adenocarcinoma. Their MRI and the morphologic appearances were compared between the two groups. Results: In 9 cases of lung squamous-cell carcinoma, the MRI signal appeared as inhomgeneous slightly hyperintense on T2 weighted images in 5/9, which were proved pathologically as main necrosis; in 7 cases of adenocarcinoma, the MRI signal appeared as inhomgeneous slightly hyperintense on T2 weighted images in 5/7, which were proved pathologically as main fibrous septum. There were statistical difference of signal intensity on T2 weinghted images between the two groups(P<0.05) The signs of lobulation and obstructine changes in lung squamous-cell carcinoma (diameter over 5cm) were seen more than in adenocarcinoma. Conclusion: Recognition of the MRI features of lung squamous-cell carcinoma and adenocarcinoma is help full in differential diagnosis of these tumors.
