摘　　要：简要介绍正电子发射断层显像 (PET)的原理、主要标记物和示踪剂。通过比较1 1 C 醋酸和1 8F FDG代谢在肝细胞癌 (HCC)的PET中的价值 ,阐述双核素技术在PET检查中的重要性 ;同时 ,通过介绍1 1 C标记的示踪剂使用条件 。The article introduces the principle of position emission tomography(PET),radiolabeling substance and radiotrace.Through comparing the different values between 11 C Acetate and 18 F FDG in HCC(Hepatocellular Carcinoma)imaging,it states the importance of using these two kinds of radiotracer to detect tumor in PET examination.Meanwhile,the article also discusses the applicative condition of 11 C Acetate in PET imaging,which demonstrates that the selection of crystal plays a key role in applying different radiotrace in PET imaging.
