超声造影区分肝硬化患者肝细胞性肝癌和肝血管瘤
Journal of Hubei University of Medicine(2012)
Abstract
目的:探讨超声造影(Contrast-enhanced ultrasonographic,CEUS)鉴别肝硬化患者中肝细胞性肝癌(Hepatocellular carcinoma,HCC)和肝血管瘤(Hepatic Hemangioma,HCH)的价值。方法:分析50例肝硬化患者肝脏实质性占位病变的超声造影表现,其中29例肝细胞性肝癌,21例肝血管瘤,并与常规超声及病理结果对照。结果:96.6%HCC患者动脉相快速均匀增强,门静脉相快速减退为等增强或低增强,延迟期持续低增强。91.5%HCH患者表现为动脉相周边环状高增强,门脉相由周边环状或结节状高增强向中央向心性增强,延迟相为持续整体增强,中央可无增强。超声造影诊断HCC的敏感性、特异性、正确率分别为96.6%、91.5%、94.3%。结论:CEUS鉴别肝硬化患者的HCC和HCH,效果优于常规超声,HCC和HCH在CEUS中表现为不同的灌注特点。
