摘　　要：肝癌是消化系统中一种常见的恶性肿瘤,早期诊断和早期治疗对病人的预后和治愈率的提高至关重要。能谱CT作为一种先进的成像技术,其扫描速度快、成像参数丰富、辐射剂量低,可以为疾病的诊断提供更多信息,近几年其应用得到飞速发展。简要介绍能谱CT的原理并综述能谱CT在肝癌诊断方面的研究进展。与常规CT技术相比,能谱CT为肝癌的鉴别诊断提供了定量依据,也为肝癌的研究提供了一个新的途径。Liver cancer is a common digestive malignant cancer. Early diagnosis and early treatment are important for the prognosis of the patients and the improvement of the cure rate. As an advanced imaging technique, spectral CT provides plenty of information for the diagnosis with the advantages of high scanning speed, multiple imaging parameters and low radiation dose, hence the spectral CT has been rapidly applied in recent years. In this review, we briefly introduced the principle of spectral CT, and summarized the research progress of spectral CT in the diagnosis of liver cancer. Compared to the previous CT techniques, spectral CT can provide quantitative measures for the differential diagnosis of liver cancer, and is a new tool for the scientific research of liver cancer.
