    Abstract

    Local ablative therapies and loco-regional therapies are being increasingly used for the purpose of providing local control of primary liver tumors and liver metastases while sparing normal liver tissue. in this manuscript, literature on the use of fluorodeoxyglucose positron emission tomography (FDG PET) to monitor local and locoregional treatment for hepatocellular carcinoma (HCC) and liver metastases, mainly limited to radio,frequency ablation (RFA) and selective internal radiation therapy (SIRT) is reviewed. Available data obtained primarily in secondary liver tumors and to a lesser extent in HCC support the notion that FDG PET performed early after RFA provides additional information about the efficacy of local tumor ablation by differentiating post-treatment changes from residual or recurrent malignant tumor. In addition, FDG PET was shown to have an added value for the detection of tumor recurrence. Thus, FDG PET imaging may not only improve treatment evaluation but also provide an opportunity for early re-intervention following RFA. Potential problems that might occur when using FDG PET for the purpose of evaluation of RFA are false negative results due to partial volume effect when dealing with small lesions (
