肺癌是全球最常见的恶性肿瘤之一，发病率和病死率增长最快。放疗是非小细胞肺癌（ NSCLC）的主要治疗手段之一，体部立体定向放疗在肺癌的治疗中发挥着重要作用。定位是放疗的重要步骤，定位是否准确及图像清晰程度直接影响靶区勾画的准确性。正电子发射计算机断层扫描（ PET／CT）弥补了 CT 定位困难和 PET 假阳性及定位不精确的不足。该文就 PET／CT 在 NSCLC 诊断、治疗及预后评估等方面的应用予以综述。

Lung cancer is one of the world′s most common malignancies,with the fastest growth of mor-bidity and mortality.Radiotherapy is one of the main treatments for non-small cell lung cancer( NSCLC) ,and stereotactic body radiotherapy technology plays an important role in the treatment of lung cancer .Positioning is an important step,accurate radiotherapy positioning and image clarity degree directly affect the accuracy of the outlining of the target.Positron emission tomography/computer tomography( PET/CT) can make up the difficulties of CT positioning,and false-positive and inaccurate of positioning with PET.Here is to make a review of the application of PET/CT in the diagnosis,treatment and prognosis of NSCLC.
