FIGURE 10. Patient (83-y-old man) with hepatocellular carcinoma of right liver lobe after transarterial chemoembolization. (A) On transverse contrast-enhanced CT image hyperdense chemoembolizing agents were visible, but differentiation of viable tumor tissue from normal liver parenchyma and necrotic tumor areas was difficult. PET image (B) clearly demonstrated residual viable tumor that could be accurately localized based on PET/CT data (C). By providing accurate anatomic localization of remaining tumor tissue, PET/CT aided further interventional planning.
