Abstract： 目的研究螺旋CT双期增强扫描低密度小肝癌的CT表现及其病理学基础.方法分析经手术病理证实的螺旋CT双期增强扫描表现为低密度的小肝癌25例共27个病灶的CT征象和病理学改变.结果 (1)平扫病灶边界模糊不清者有16个病灶,边界清楚者有11个病灶;增强后病灶边界模糊者只有7个病灶,边界清楚者有20个病灶,同时病灶边缘轮廓轻度不规整.(2)平扫瘤内呈均匀性低密度者有18个病灶,瘤内密度不均匀者有9个病灶;增强后瘤内密度均匀者只有6个病灶,瘤内密度不均匀、有多个小斑点状密度更低区者有21个病灶.结论螺旋CT双期增强扫描低密度小肝癌的CT表现特点是:平扫病灶边界模糊,增强后病灶边界变清楚并呈轻度不规整,同时病灶内密度不均匀,有多个小斑点状密度更低区.根据该特点可以与肝脏的其他表现为低密度的病变进行鉴别.
