Abstract: Hepatocellular carcinoma (HCC) is one of the leading causes of cancer mortality worldwide. Various imaging modalities provide important information about HCC for its clinical management. With the continuous progress of PET/CT research in oncology, it has played crucial roles in detecting, distinguishing, accurately staging, and evaluating local, residual and recurrent HCC. Dual tracer technology has become an important technology to assist HCC diagnosis, and the advent of new radiotracers has improved the ability to detect lesions. This paper reviews the current status of PET/CT for HCC.
