18F-脱氧葡萄糖(FDG)PET/MR在非小细胞肺癌(NSCLC)诊治的应用逐渐广泛。与PET/CT相比，PET/MR具有软组织对比度高、辐射少、多参数成像、能够提供更多功能参数等优点。该文综述了n 18F-FDG PET/MR在非小细胞肺癌诊断、分期、再分期和预后评价等方面的应用。n “,”18F-fluorodeoxyglucose(FDG) PET/MR has been more and more widely used in non-small cell lung cancer (NSCLC). Compared with PET/CT, PET/MR has more advantages, such as higher contrast resolution of soft tissues, less radiation dose and providing physicians with more functional parameters. This article summarizes the application status of n 18F-FDG PET/MR in NSCLC in terms of diagnosis, staging, restaging, and prognosis.n
