1、·医学影像·中国现代医生2014年5月第52卷第15期多层螺旋CT三期增强扫描对原发性肝癌的诊断及鉴别诊断价值李加其四川省雅安市第二人民医院放射科,四川雅安625000[摘要】目的探讨多层螺旋CT三期增强扫描对原发性肝癌的诊断及鉴别诊断价值。方法随机选取2010年8月~2013年8月我院收治的肝部占位性病变患者72例进行回顾性分析,其中原发性肝癌患者32例,肝血管瘤患者18例,肝转移癌12例,肝内胆管细胞癌l0例。结果32例原发性肝癌患者动脉期强化病灶49个,门静脉期低密度病灶52个,延迟期24例密度低于临近的肝组织,8例呈等密度。12例肝转移癌患者动脉期及门静脉期均
2、显示边缘连续环状强化,中央区供血少,可见“牛眼征”,延迟期呈低密度表现。18例肝血管瘤患者动脉期26个病灶结节状边缘,门静脉期病灶内增强范围增大,影像密度均匀及下降,延迟期几乎所有病灶均强化,密度接近于肝脏实质。10例肝内胆管细胞癌动脉期有5例出现病灶边缘环状强化斑,3例片状不均匀强化,2例不强化;门静脉期轻度不规则斑块样强化2例;延时期有4例不同程度向心性强化,密度稍高于正常的肝组织,网格样强化3例。结论多层螺旋CT三期增强扫描对原发性肝癌的诊断及鉴别诊断提供可靠的依据,值得临床推广。【关键词】多层螺旋cT;动脉期;门静脉期;延迟期;原发性肝癌【中图分类号]R735
