Abstract

Hepatocellular carcinoma (HCC) is one of the most common malignant lesions and the third leading cause of cancer death, after lung cancer and stomach cancer. HCC has a bad prognosis, in the early stage, the clinical symptoms are poor and difficult to diagnose. The majority of cases are diagnosed in the advanced or late stage. The imaging facilities have been playing an important role in the definitive diagnosis of HCC and post-treatment follow-up. In which, computed tomography (CT) is a routine survey technique, but this method still has some limitations in many cases such as small tumor size, atypical contrast media enhancement, or local recurrence after embolization,… In recent years, the role of spectral CT in the diagnosis and post-treatment assessment of HCC has been increasingly confirmed, and contributes to overcoming the aforementioned limitations.
