【摘要】 肝脏是人体最大的腺体。肝脏占位性病变是临床上常见的一种肝脏疾病,其病理类型十分复杂,且治疗方法和预后显著不同,因此其鉴别诊断是临床急需解决的重要问题之一。近年来,随着第二代造影剂和低机械指数实时扫描技术的应用,超声造影作为一项非侵入性技术,利用超声造影剂使肝内血管、肝组织及肝内病灶显影,从而实时评价肝脏血管灌注的整个时期,并根据不同的特征性表现,显著提高了肝脏占位性病变的诊断准确率。本文就肝脏各种占位性病变的超声造影表现特征进行综述。更多还原

【Abstract】 The liver is the largest gland in the body. Focal liver lesions are the clinical common liver diseases with complex pathological types. Their treatment and prognosis are significantly different. So the differential diagnosis of focal liver lesions becomes urgent in clinic. In recent years, the second generation contrast agents and the low mechanical index realtime scanning technology have developed rapidly. As a noninvasive technique, contrast-enhanced ultrasound can clearly display the intrahepatic vessels, intrahepatic tissues and intrahepatic lesions, then evaluate the period of vascular perfusion in the liver to improve the diagnostic accuracy. The contrast-enhanced ultrasonographic features of different focal liver lesions are reviewed in the present paper.更多还原
