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。
The liver is the body’s largest gland. Liver space-occupying lesions are a common clinical liver disease, the pathological type is very complicated, and the treatment and prognosis are significantly different, so the differential diagnosis is one of the most important issues to be solved clinically. In recent years, with the second generation of contrast agent and low mechanical index real-time scanning technology, ultrasound contrast as a noninvasive technology, the use of ultrasound contrast agent to intrahepatic blood vessels, liver tissue and intrahepatic lesions development, real-time evaluation Throughout the period of hepatic vascular perfusion, and according to different characteristic manifestations, the diagnostic accuracy of liver space-occupying lesions was significantly improved. This review summarizes the features of various contrast-enhanced ultrasound lesions of the liver.
