摘要 目的观察超声造影(CEUS)中肝脏占位性病变(FLL)的不同图像特点,初步探讨超声造影在原发性肝癌(HCC)及肝血管瘤病变的鉴别诊断中的应用价值。方法对53例肝占位性病变进行实时超声造影检查,其中32例原发性肝癌,21例肝血管瘤,全部病例均经病理证实。分析两组病例常规超声图像及CEUS灌注特点,探讨两种病变的鉴别诊断特征。结果经超声造影后,HCC表现多为动脉相快速显影,门脉相快速消退,呈"快进快出"型;肝血管瘤动脉相时无明显变化,增强方式以门静脉期周边缓慢增强,呈向心样填充,造影剂显影持续时间较长。结论HCC及血管瘤在实时超声造影中能表现出不同的时相特点,可以帮助提高超声诊断的特异性、敏感性及准确性。
