<qa>  What is the unique metabolic pathway of glucose in the HCC cells?The value of the FDG PET for evaluation of HCC is controversial, in particular due to the unique metabolic pathway of glucose in the HCC cells. Since 2007 more and more studies suggest the feasibility of FDG PETCT for monitoring local recurrence especially after RF and metastatic spread of HCC, including detection of active disease only suspected by AFP alphafoetoprotein elevation.
