Role of [18F]FDG-PET/CT after radiofrequency ablation of liver metastases: preliminary results

Purpose Focal metastasis may be treated with radiofrequency ablation (RFA), a low invasive method yet limited by the lack of direct evidence of radicality of treatment. We, hereby, aimed at assessing the role of positron emission tomography–computed tomography (PET/CT) with fluoride radiolabeled deoxy-glucose ([18F]FDG) in RFA treatment success evaluation and early diagnosis of local relapse of liver metastasis after RFA...
