【摘要】 目的探讨超声造影剂(SonoVue)与实时灰阶造影匹配成像技术观察肝脏局灶性病变的灌注过程、回声变化规律以及对肝恶性肿瘤诊断的应用价值。方法分析采用静脉快速团注造影剂SonoVue法对39例肝脏局灶性病变造影剂灌注过程。结果39例中36例超声造影表现符合欧洲医学和生物学超声协会联盟(EFSUMB)对肝脏局灶性病变良、恶性超声造影诊断标准,2例假阳性,1例假阴性。超声造影判别恶性肝脏局灶性病变(focal liver lesion,FLL)的敏感性为95.83%,特异性为86.67%,阳性预测值92.00%,阴性预测值92.86%,准确性92.30%。结论实质灰阶超声造影有助于肝局灶性病变的良恶性判断。更多还原

【Abstract】 Objective To evaluate the diagnostic value of new contrast agent and real time gray-scale contrast ultrasonography in focal liver lesions.Methods Thirty nine cases with focal liver lesions were enrolled in the study.Contrast agent SonoVue,Technos DU8 and Logiq9 and their contrast technology were used.The contrast agent was delivered through bolus injection.Results The diagnostic sensitivity,specificity,positive and negative rate and accuracy were 95.83%(23/24),86.67%(13/15),92.00%(23/25),92.86%(13/14) and 92.30%(36/39),respectively.Conclusion Contrast-enhanced gray-scale ultrasonography could play an important role in differential diagnosis of focal liver lesions.更多还原
