摘要
为使肺癌得到正确的诊断和治疗 ,应用新的肺癌国际TNM分期标准是十分重要的。由于CT有助于在肺癌诊断和分期过程中对于原发肿瘤和纵隔淋巴结的评估 ,同时也有助于搜寻远处转移灶。因此 ,CT是肺癌最重要的辅助影像检查 ,而且也可进一步明确观察大气管、大血管、淋巴结及胸膜受侵犯的情况 ,从而为肺癌的TNM分期提供更有价值的信息和资料。PET CT的图像融合可使肺癌的定位更加准确 ,使解剖位置和病灶代谢两者关系更为完善。PET/CT的联合检查和图像融合可改进肺癌的术前TNM分期 。
In order to achieve correct diagnosis of lung cancer for therapeutic planning, it is important to apply the new international TNM staging system. CT can be helpful in diagnosis and staging of lung cancer with regard to evaluation of the primary tumor and mediastinal lymph nodes and in the search for sites of distant metastasis. Therefore, CT is the most important supplementary examination for lung cancer, which can give further observation of the invading standard of large bronchus, vessels, lymph nodes and pleura, which might provide more valuable information for TNM staging.PET CT image fusion permits superior localization of lung cancer. The relation between anatomic and metabolic volume is more complex. Combined PET/CT and image fusion will improve the TNM classification in preoperative staging of lung cancer which may result as the best non invasive method.
