摘　　要：目的:探讨超声造影在肝脓肿与肝脏恶性肿瘤鉴别诊断中的价值。材料和方法:对临床和病理确诊的20例原发性肝癌、11例肝转移癌和11例肝脓肿进行常规超声检查和超声造影检查。比较肝脏恶性肿瘤与肝脓肿的造影表现特征。绘制时间强度曲线,定量分析比较两类病变造影的始增时间、达峰时间和增强持续时间。结果:肝脓肿超声造影异常灌注区范围显著大于灰阶超声显示病变区(P<0.01),而肝脏恶性肿瘤超声造影异常灌注区范围与灰阶超声显示病变区范围无显著差异(P>0.01);肝脓肿超声造影的始增时间,达峰时间及增强持续时间显著小于肝脏恶性肿瘤(P<0.01)。结论:肝脓肿和肝脏恶性肿瘤超声造影的不同表现特征在两类病变的鉴别诊断中有重要价值。Purpose： The study was designed to investigate the role of contrast-enhanced ultrasound in the differential diagnosis of hepatic abscesses from malignant tumors. Materials and Methods： Forty-two patients with pathologic or clinical follow-up proven hepatic lesions （20 hepatic primary carcinoma, 11 hepatic metastases and 11 hepatic abscesses） were explored using both conventional and contrast-enhanced ultrasound. Features of sonogram and time-intensity curves were compared between hepatic abscess and hepatic malignancy. Results： Lesion＇ s dimension demonstrated on contrast-enhanced ultrasound was significantly lager than that depicted by gray scale ultrasound in hepatic abscess （P 〈 0.01 ）, but for hepatic malignant tumor, size of lesions revealed on gray scale ultrasound and contrast enhanced ultrasound was almost the same. Significant difference was found in the time to enhancement, time to peak intensity and enhancement duration between hepatic abscesses and hepatic malignant tumors （P 〈 0.01 ）. Conclusion： Characteristics demonstrated by contrast enhanced ultrasound will facilitate the differential diagnosis of hepatic abscess and hepatic malignancy.
