摘要
恶性肿瘤已成为目前危害人类生命健康的最严重疾病之一,早期发现及治疗是改善预后的关键。肿瘤筛查是早期发现肿瘤和癌前病变的重要途径。随着人们对肿瘤筛查手段要求的提高,PET这一高端影像学检查技术已越来越多地应用于肿瘤筛查。虽然大量数据显示PET可在人群中发现一些亚临床的恶性肿瘤,但在当代医疗实践中,PET用于肿瘤筛查依然存在很大的争议。该文旨在分析PET在目前肿瘤筛查方面的应用现状和存在的问题,以及对肿瘤筛查的意义和价值。

Though a great number of data show that PET can find some subclinical malignancy, yet as a cancer screening modality, PET is still controversial in contemporary medical practice. The aim of this article is to review the application status and existing problem of PET in cancer screening, and to offer some recognition and view about cancer srceening.
