摘要
目的:探讨脂肪肝内血管瘤的常规超声特点,定量分析脂肪肝及其内血管瘤的超声造影血流灌注情况。方法:对比分析脂肪肝内血管瘤及正常肝内血管瘤的二维超声特点,分析比较两种肝实质背景及其内血管瘤的超声造影定量参数。结果:与正常肝内血管瘤相比,脂肪肝内血管瘤常规超声低回声、边界不清及后方回声增强者较多且常规超声对脂肪肝内血管瘤的正确诊断率较低(P<0.05);与正常肝相比,脂肪肝背景超声造影到达时间延迟且峰值强度低于正常肝,中、后场造影峰值时间延迟(P<0.05)。结论:脂肪肝内血管瘤常规超声表现缺乏典型的声像图特征,诊断较困难;脂肪肝的超声造影血流灌注效应低于正常肝。
Objective：To investigate the conventional ultrasound characteristics of the fatty hepatic hemangioma,quantitatively analyze the ultrasound contrast blood perfusion characteristics of fatty liver and hemangioma.Method：To comparatively analyze the conventional ultrasound characteristics of fatty hepatic hemangioma and normal hepatic hemangioma.Analyze the contrast parameters of the two hepatic background and hemangioma.Result：Compared with the normal liver,amounts of hypoecho,ill-defined and posterior echo enhancement in fatty hepatic hemangioma were more,and the rate of correct diagnosis was lower for fatty hepatic hemangioma（P0.05）.Compared with normal hepatic background,arrival time of contrast agent in fatty hepatic background was later and the peak intensity was lower than normal liver（P0.05）.Time to peak of midfield and posterior field was later than normal liver（P0.05）.Conclusion：Fatty hepatic hemangioma has show unusual patterns in conventional ultrasound,it is difficult to diagnose.Fatty hepatic perfusion effect is lower than normal liver in contrast-enhanced ultrasonography.
