实时超声造影在肝脏局灶性病变诊断中的应用

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.

Clinical Study of Real Time Contrast-enhanced Ultrasound on Differential Diagnosis of Focal Liver Lesions

Objective:To evaluate the availability and significance of real time contrast-enhanced ultrasound on diffe-rential 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.
