【摘要】 目的探讨心源性肝淤血的多层螺旋CT(multi-slice spiral CT,MSCT)征象。方法对21例心源性肝淤血的MSCT图像进行回顾性研究,分析心源性肝淤血的MSCT征象。结果21例心源性肝淤血患者MSCT扫描动脉期均出现不同程度的下腔静脉逆向显影,其中合并肝脏异常灌注者10例,淋巴郁滞征象者7例。结论肝脏MSCT增强扫描动脉期出现的下腔静脉逆流征象和肝脏异常灌注常提示心源性疾患右心压力增高所致肝脏淤血可能。更多还原

【Abstract】 Objective To study multi-slice spiral CT(MSCT) features of cardiogenic hepatohemia.Methods MSCT features of cardiogenic hepatohemia were retrospectively analysed.Results All cases were showed having reflux of contrast into the inferior vena cava(IVC)during arterial phase,of them,10 cases were accompanied with abnormal hepatic perfusion and 7 cases with intrahepatic lymphostasis sign.Conclusion The features including the reflux of IVC and abnormal hepatic perfusion during arterial phase in contrast-enhanced CT scan may suggest hepatohemia caused by higher pressure level of right heart from the cardiovascular diseases.更多还原
