摘　　要：目的探讨实时超声造影成像技术在肝脏局灶病灶鉴别诊断中的价值。方法 77例肝脏良恶性病灶中,良性31例,恶性46例。采用GE-LOGIQ9彩色多普勒诊断仪,使用声诺维进行超声造影成像,实时记录肝实质及病灶的充填过程、充盈方式及增强程度。结果肝恶性病灶:早期动脉相95.6%(44/46)病例出现造影增强图像,延迟相97.8%(45/46)病例呈低增强(2例肝细胞癌呈等增强)。肝良性病灶:早期动脉相51.6%(16/31)病例出现造影增强图像,延迟相96.8%(30/31)病例呈等增强和高增强(1例血管瘤呈低增强)。结论实时超声造影能反映不同肝脏病变血流灌注的特征,对肝脏良恶性肿瘤的鉴别诊断有重要价值。Objective To investigate the value of contrast-enhanced sonography in differential diagnosis of benign and malignant focal hepatic lesions.Methods Malignant（46 cases）and benign（31 cases）lesions of the liver were examined by GE_LOGIQ9 color Doppler ultrasound system with contrast-enhanced ultrasonography software and sonovue.The engorged process and type,enhanced extent of hepaticparenchyma and masses were recorded.Results 95.6%（44/46）malignant lesions showed contrast enhancement in the early phase,and 97.8%（45/46）malignant lesions showed hypoechoie in the late phase.51.6%（16/32）benign lesions showed contrast enhancement in the early phase,and 96.8%（30/31）benign lesions showed isoechoic and hyperechoic in the late phase.Conclusion Contrast-enhanced sonography with sonovue has a greater clinical value in the differentiation of benign and malignant 1iver lesions.
