目的：探讨螺旋CT动态多期扫描模式在肝细胞癌临床诊断中的意义。方法：选取2008年至2013年经病理诊断确诊为肝细胞癌的患者83例，对患者CT 扫描的影像学资料进行回顾性分析。结果：螺旋CT扫描中动脉期、门静脉期、延迟期的检出率均显著高于平扫模式（ P＜0．05）。平扫模式检出52例信号为低密度或等密度，增强动脉期明显强化81例，门静脉期67例主要表现为低密度信号，延迟期75例患者信号为低密度，变化特点为速升速降。结论：螺旋CT动态多期扫描相比平扫局域检出率更高，还能够更清楚反映肝细胞癌的特征，对肝癌早期诊断有较高的临床价值。

Objective:To observe the significance of dynamic and multiple-phase scanning of spiral CT for diagnosing hepatocellular carcinoma.Method:83 cases with hepatocellular carcinoma treated in our hos-pital from 2008 to 2013 were selected, and the imaging data of CT scanning of patients was analyzed retro-spectively.Result:The positive rate of arterial phase, portal venous phase and lag phase of spiral CT scan-ning was evidently higher than those of plain scan ( P<0.05) .Scan mode detected that the signal of 52 cases was low density or equal density, there were 81 cases with evident enhancement in arterial phase.The mani-festation of 67 cases in portal vein phase was low-density signal.And the signal of 75 cases in delay phase was low density, and the variation characteristic was raising and reducing greatly.Conclusion: Compared with plain scan, the positive rate of dynamic and multiple-phase scanning of spiral CT is higher,and it can clearly reflect the features of hepatocellular carcinoma, which has higher clinical value for early diagnosis of hepatocellular carcinoma.
