肺癌的鉴别诊断一直是困扰影像工作者的一大难题，能准确地将肺癌与肺内良性病灶鉴别开来将会使临床很大程度上受益。正电子发射型计算机断层显像-计算机 X 线体层扫描（PET-CT）自问世以来，就已经开始投入到肺癌诊断与鉴别诊断的应用中。到底 PET-CT 对肺癌鉴别诊断的价值如何以及其在肺癌鉴别诊断研究应用中有哪些发展方向？该文就 PET-CT 在肺癌鉴别诊断中的相关研究进展情况进行综述，主要介绍了 PET-CT 在肺癌鉴别诊断的应用现状、新 PET 显像剂的研究、PET-CT 定量分析、PET-CT 延迟显像以及药物介入 PET-CT 显像。

The differential diagnosis of lung cancer has been a challenge for imaging physicians.Accurately identifying lung cancer from benign pulmonary lesions can yield signifi-cant clinical benefit.Since the advent of PET-CT,it has been applied in the diagnosis and dif-ferential diagnosis of lung cancer.Clinical value and application orientation of PET-CT in the diagnosis and differential diagnosis of pulmonary cancer remain to be elucidated.In this study, research progress of PET-CT in differential diagnosis of lung cancer was summarized,mainly including present situation of the application of PET-CT in differential diagnosis of lung cancer, novel PET imaging agents,PET-CT quantitative analysis,PET-CT delayed imaging,PET-CT imaging before and after drug intervention.
