目的：分析肺癌空洞的Ｘ线平片、ＣＴ与ＭＲＩ表现，探讨空洞与肿瘤类型及分化程度关系。材料与方法：对４０例以各种方法证实为肺癌，均摄Ｘ线平片，其中３０例做ＣＴ、１０例做ＭＲＩ检查。４０例中３０例手术病理检查，病理结果与影像表现对照。结果：空洞内缘不规则似癌梁样改变，空洞壁厚度与空洞在肿瘤中位置特别是肿瘤越小，形成的空洞越小；肿瘤越大，空洞偏大，且肿瘤又呈分叶样改变等与肿瘤类型与分化程度有明显关系。ＣＴ对空洞内缘与肿瘤边缘显示优于Ｘ线平片。ＭＲＩ对肿瘤组织信号强度变化，如肿瘤液化坏死，甚至对肿瘤性质有潜在定性能力。结论：肺癌空洞Ｘ线、ＣＴ与ＭＲＩ表现与肿瘤类型及分化程度有明显联系。
OBJECTIVE: To analyze the x-ray plain film, CT and MRI features of lung cancer, and to explore the relationship between cavitation and tumor type and differentiation. Materials and Methods: Forty cases of lung cancer were confirmed by various methods. All patients received X-rays, of which 30 were performed CT and 10 were performed MRI. Thirty out of 40 cases were pathologically examined and the pathological results were compared with the image performance. RESULTS: The inner edge of the cavity was irregularly shaped like a cancer beam. The thickness of the cavity wall and the location of the cavity in the tumor, especially the smaller the tumor, the smaller the formation of cavities; the larger the tumor, the larger the cavity, and the tumor showed lobular changes. It has a significant relationship with tumor type and differentiation. CT showed better than X-ray film on the inner edge of the cavity and the tumor edge. MRI changes the signal intensity of tumor tissue, such as tumor liquefaction and necrosis, and even has the potential qualitative ability to tumor properties. Conclusions: There is a clear correlation between the features of lung X-ray, CT and MRI, tumor type and differentiation.
