Core Tip

Core tip: Positron-emission tomography (PET) is an effective and noninvasive modality for visualizing hepatocellular carcinoma (HCC). This paper reviews the clinical utility of PET for HCC, including the detection of intrahepatic or extrahepatic lesions, differential diagnosis, prediction of differentiation and prognosis, and evaluation of therapeutic response. Complementary technologies, such as dynamic blood flow and dual-phase and dual-tracer PET imaging, are also mentioned. Novel radiotracers and immuno-PET have shown great potential for PET imaging and have become the focus of current research, which may enhance the diagnostic capability of PET for HCC. An overview of the current PET diagnostic status of HCC is reviewed.
