全肝多期增强动态CT扫描在肝硬化及慢性肝炎病人的影像学检查中起重要作用。肝硬化常可进展为肝细胞癌(H CC)或癌前病变,如发育不良性结节(DN)。典型H CC呈富血供,且在增强检查的动脉期易检出,但某些分化较好的H CC或DN血供相对较少,常仅在延迟期才能发现。肝实质强化程度取决 Whole liver multi-phase enhanced dynamic CT scan in cirrhosis and chronic hepatitis patients imaging plays an important role. Cirrhosis often progresses to hepatocellular carcinoma (HCC) or precancerous lesions such as dysplastic nodules (DN). Typical H CCs are blood-rich and are readily detectable during the arterial phase of enhanced examinations. However, relatively well-differentiated H CC or DN blood donations are relatively rare and are often found only in the delayed phase. Intensive liver depends on the degree
