多模态影像鉴别中央型肺癌和肺不张研究进展

Research progress on the identification of central lung cancer and atelectasis using multimodal imaging

中央型肺癌临床常见,多发生在段支气管以上,由于其多伴发支气管狭窄或阻塞,故易引发肺不张。准确区分肺癌与肺不张,对于肿瘤分期、勾画放疗靶区以及评价疗效均具有重要意义。本文就如何基于多模态影像划分中央型肺癌与肺不张边界,对国内外文献进行回顾,以期总结经验、展望发展方向。

Central lung cancer is a common disease in clinic which usually occurs above the segmental bronchus.It is commonly accompanied by bronchial stenosis or obstruction,which can easily lead to atelectasis.Accurately distinguishing lung cancer from atelectasis is important for tumor staging,delineating the radiotherapy target area,and evaluating treatment efficacy.This article reviews domestic and foreign literatures on how to define the boundary between central lung cancer and atelectasis based on multimodal images,aiming to summarize the experiences and propose the prospects.
