【摘要】 目的：评价CT预测肺癌手术可行性的意义。材料与方法：对47例肺癌患者术前的CT预测与手术结果进行比较。作为不可根治的CT阳性表现如下：（1）肿瘤周围的大血管受侵，（2）肺门和纵隔淋巴结转移，（3）肿瘤侵及胸壁、胸膜、心包、横膈等组织。结果：正确预测不可根治13例，错误预测不可根治5例，正确预测可根治28例，错误预测可根治1例。结论：当CT仅提示一种阳性征象，并不能作为手术的禁忌征，反之，同时出现一种以上阳性表现，则应充分认识其不可根治性。更多还原

【Abstract】 Purpose: To evaluate the significance of forecasting the resectability for patientswith lung cancer. Materials and methods: Among forty- seven cases of lung cancer,a comparisonbetween the CT images and the results of operations have been made. Results:The CT positivesigns were as follow: (1)Main blood vessels arrounding the tumors were involved. (2)Metastaticlymph nodes of hilum pulmonis and mediastinum. (3)Thoracic wall, pleura, pericardium and diaphragm were involved in carcinoma,et al. Conclusion: If there were some of these positive signssimultaneously, the unresectable probability should been considered fully. However, when haveonly sigle positive sign,it didn’t mean that is absolute contraindication of surgical resection.更多还原
