探讨多层螺旋CT动脉期对肝海绵状血管瘤的诊断价值

目的:探讨多层螺旋CT动脉期对肝海绵状血管瘤的诊断价值。方法:回顾分析45例共59个病灶,经手术病理或肝血管造影介入治疗证实的肝海绵状血管瘤,全部病例均行多层螺旋CT平扫,动、静脉双期扫描和延期扫描。结果:59个病灶平扫均表现为圆形或类圆形低密度区。病灶动脉期表现为:病灶边缘呈结节状强化32个。病灶边缘呈斑点状强化12个。病灶边缘呈小结节并半环状强化9个。病灶边缘呈小点状强化6个。静脉期全部病灶强化区扩大。延时期55个病灶填满强化,密度等于肝实质或略高于肝实质,4个病灶中央无强化。结论:多层螺旋CT动脉期对肝海绵状血管瘤有重要诊断价值。

The Diagnostic Value of Arterial Phrase in Hepatic Scanning by Multiple-slices Spiral CT to Cavernous Hemangioma of Liver

Objective To investigate the diagnostic value of arterial phrase in hepatic scanning by multiple-slices spiral CT to cavernous hemangioma of liver.Methods 59 focuses in 45 patients were analyzed retrospectively and confirmed as cavernous hemangioma of liver by pathological examination or the interventional therapy of liver.The arterial phase,portal vein phase,hepatic plain scan and delayed scanning in hepatic scanning by multiple-slices spiral CT were performed in all cases.Results There was round-shape or round-shape like low density area in plain scanning of 59 focuses.The appearance of arterial phase in focuses displayed the nodosity enhancement in 32 focuses,the mottling enhancement in the fringe of 12 focus,the little tubercle and semi-ring enhancement in the fringe of 9focus,the dot enhancement in the fringe of 6 focus.The enhanced areas in all focuses expanded in portal-vein phase.55 focuses were fully enhanced in delayed phase.The densities of focuses were equal to,or higher than that of liver parenchyma.There were no enhancements in the center of 4 focuses.Conclusion Arterial phrase in hepatic scanning by multiple-slices spiral CT is valuable for diagnosis of cavernous hemangioma of liver.
