摘　　要：目的 :评价结节型肝细胞癌在螺旋CT增强扫描中 ,其动脉期、门脉期、延迟期的病灶检出率。材料与方法 :2 4例结节型肝细胞癌行螺旋CT检查 ,先平扫 ,再以 3ml 秒团注对比剂 15 0ml,分别作动脉期 (注射后 2 5秒 )和门脉期 (注射后 60～ 70秒 )、延迟期扫描 (注射对比剂后 4～ 6min)。观察病灶的强化方式 ,统计各期的病灶检出率。结果 :这 2 4例共发现肿瘤病灶 45个 ,平扫、动脉期、门静脉期、延迟期扫描的病灶率分别是 2 3 5 %、 84 3 %、 66 7%、 72 5 %。结论 :螺旋CT增强扫描能显示结节型肝细胞癌的强化特点 。Purpose:To evaluation the detected rate of nodular hepatocellular carcinomas(HCC) on spiral CT enhanced scanning of arterial-,portal-,and delay phase.Materials and Methods:Spiral CT scanning was performed in 24 cases nodular HCC,After plain CT examination,performed arterial phase(25s after injection) and portal venous phase (60～70s after injection)、delay phase(4～6min after injection) with a 150ml bolus injection of contrast material at 3ml/s.The morphology and characteristics on enhanced scans were analyzed and the numbers of the detected lesions were calculated on each phase.Results:45 nodular HCC of total 24 cases were found,the detected rate on plain scan、arterial phase、portal venous phase and delay phase were 23 5%、84 3%、66 7%、72 5% respectively.Conclusion:spiral CT enhanced scanning can fully show the enhanced characteristics of HCC,and combination of three phases could improve the detected rate.
