摘要
目的:评价实时超声造影技术在肝脏局灶性病变诊断中的作用及意义。方法:采用实时超声造影技术,对我院269例肝脏局灶性病变进行超声造影检查。结果:92.4%恶性病变动脉相呈现回声增强。病灶动脉相呈现高增强或等增强、延迟相消退为低增强或无增强,在良性病变中占13.8%(19/138),恶性病变中为94.7%(124/131);实时超声造影诊断肝脏局限性病灶的敏感度89.6%,特异度97.5%,诊断符合率93.2%。结论:实时超声造影可显示肝局灶性病变的血流灌注特点,对肝局灶性病变的分类诊断有重要的应用价值。
Objective：To evaluate the availability and significance of real time contrast-enhanced ultrasound on differential diagnosis of focal liver lesions. Methods：Real time contrast-enhanced ultrasound was used for differential diagnosis of focal liver lesions in 269 cases. Results：92.4 % of malignant focal liver lesions showed echo enhancement during the arterial phase. Lesions with hyper- or iso-enhancement during arterial phase then subsided to hypo- or non-enhancement in late phase, the benign focal liver lesions was 13.8 % （19/138） whereas the malignant focal liver lesions was 94.7 % （ 124/131 ）. In this study the sensitivity, specificity and accuracy of diagnosis of focal liver lesions with real time contrast-enhanced ultrasound were 89.6 %, 97.5% and 93.2 % respectively. Conclusion：Real time contrast-enhanced ultrasound is sensitive and accurate in demonstrating hemodynamic features of focal liver lesions, and it can be a promising technique on differential diagnosis of focal liver lesions.
