摘　　要：目的:观察超声造影在肝转移癌患者中的诊断价值.方法:临床采用超声造影技术对55例诊断为恶性肿瘤并经超声检测高度怀疑存在肝占位患者进行影像学检查,同时对55例患者进行普通超声.观察并记录两种影像学检查下肝内病灶的大小以及数目等.结果:超声造影检查共发现53例193个病灶,普通超声共发现50例147个病灶.超声造影的灌注特征主要有4种表现形式:第1种为肿瘤周边呈快速环状强化;第2种为动脉期快速团状强化,快速廓清;第3种为动脉期至实质期病灶内均无增强;第4种为门脉期或动脉期出现延迟增强现象,而在实质后期出现轻度退出.结论:超声造影在临床诊断肝转移癌中具有较高的临床准确率,特别在病变早期,微小病灶刚形成阶段,有着较高的检测阳性率.AIM： To assess the value of contrast-enhanced ultrasound （CEU） in the diagnosis of liver me- tastases. METHODS： Fifty-five patients who were diag- nosed with a malignant tumor and focal liver lesions highly suspected of metastases under- went CEU and plain ultrasound. The size and number of intrahepatic lesions detected by CEU and plain ultrasound were recorded and com- pared.RESULTS： CEU revealed 193 lesions in 53 pa- tients, and ultrasound revealed 147 lesions in 50 patients. The perfusion characteristics of CEU had four main forms of manifestations： rapid ring enhancement of the tumor, rapid mass-like enhancement and rapid clearance during the ar- terial phase, no enhancement of the lesion dur- ing the period between the arterial phase and parenchymal phase, and delayed enhancement of the lesion during the arterial phase or portal venous phase and mild withdrawal in the paren- chyma in the later stage. CONCLUSION： CEU has a higher accuracy than plain ultrasound in the diagnosis of liver cancer, especially early liver cancer in which small le- sions are newly formed.
