摘　　要：目的探讨不同肝脏占位病变在超声造影中的增强特征。方法对45例肝脏占位病变患者进行超声造影检查,并实时观察病灶内灌注过程及回声变化。结果肝细胞肝癌表现为动脉相快速增强,并在门脉相快速消退;肝血管瘤呈现自周围向心性缓慢充填式增强或周边增强,持续较长时间;肝局灶结节性增生(FNH)表现为快速增强,在实质相开始消退;肝转移癌表现为动脉相周边增强;肝炎性假瘤(IPL)和肝硬化增生结节大多在动脉相、门脉相及实质相均未见异常增强和廓清区。结论不同性质的肝脏占位病变在超声造影中有不同的增强方式,可为肝脏占位的鉴别诊断提供依据。超声造影有良好的临床应用前景。Objective To investigate the characterization of liver space-occupying lesions in real-time contrast enhanced ultrasound. Methods 45 patients with focal hepatic lesions were examined by contrast-enhanced ultrasound. And the process of perfusion and change of echo in foci were observed. Results After injection of Sono- Vue, HCC showed the enhance greatly and quickly in arterial phase and rapid disappearance in the portal venous phase. Hepatic hemangioma showed centripetal filling enhance pattern or showed peripheral enhance and lasted for a long time. Focal nodular hyperplasia （FNH） showed enhance quickly in arterial phase but disappearence was in parenchymal phase; Hepatic metastatic carcinoma showed peripheral enhance in artery period. Most of inflammatory pseudotumor of the liver （IPL） and cirrhotic regenerative nodule of the liver didn＇t show the area of abnormal enhancement and clearance in all process. Conclusion Different liver lesions show different enhancement patterns of the contrast-enhanced ultrasound, which provide the basis for the differential diagnosis of the liver lesions. Therefore, contrast-enhanced uhrasonography has good prospect for clinical use.
