| 摘 要： | 肺癌已成为人类癌症死亡的主要原因之一,其发病率及死亡率仍在迅速增长。目前X线胸片、计算机体层摄影(computed tomography,CT)扫描能帮助医师对大部分肺癌作出诊断和分期判定,但对于一些早期病变的判定帮助有限。正电子发射断层摄影(positron emission tomography,PET)在肿瘤的早期诊断、分期和疗效评估方面有较高的敏感性和特异性,但其空间分辨力较差。PET-CT的出现弥补了这两方面的缺憾,它融合专用的PET扫描仪和CT扫描仪的技术,提供了来自两种显像方式的独特信息。本文就PET-CT在肺癌诊断中的应用进行了综述。

| Abstract: | Lung cancer has been the main death reason of human being cancer.The incidence of lung cancer and death rate increase rapidly in recent years.X ray and CT(computer tomography) scan of thorax can diagnose main part of lung cancer,but there are some difficulty in some small lung lesions.PET(positron emission tomography) have high sensitivity and specificity in early diagnosis,stage and curative effect evaluation of lung cancer,but the space distinguishing is bad.PET-CT can make up these drawbacks.It have the dedicate PET and CT scanner.PET-CT can provide the special information of the two imaging mode.This is a review about the application of PET-CT in the diagnosis of lung cancer. |
