目的研究“慢进快出”型肝细胞肝癌(hepatocellular carcinoma,HCC)螺旋CT(SCT)检查价值。资料与方法分析经手术病理证实的50例HCC的CT表现。结果50例中18例SCT增强扫描表现为“慢进快出”型,动脉期病灶强化,门静脉期病灶密度不下降,反而进一步升高,延迟期强化密度迅速下降。结论SCT增强扫描呈“慢进快出”型表现与其肝动脉和门静脉的双重血供有关,似与肿瘤分化程度不相关。 Objective To study the value of spiral CT (SCT) examination of hepatocellular carcinoma (HCC). Materials and Methods CT findings of 50 HCC confirmed by surgery and pathology were analyzed. Results In 50 cases, 18 cases of SCT enhanced scans showed “slow and fast” type. The arterial phase was enhanced and the density of portal venous phase did not decrease. On the contrary, the SCT increased further and the densification intensity decreased rapidly. Conclusion The SCT enhanced scan showed a “slow to fast out” type of performance and its hepatic artery and portal vein of the double blood supply, it seems irrelevant to the degree of tumor differentiation.
