| Abstract: | 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. |
