常规超声与超声造影对肝内良恶性结节的鉴别价值

Value of conventional ultrasound and contrast-enhanced ultrasound in differentiating benign and malignant nodules in the liver

目的 探究超声造影(CEUS)在肝内结节良、恶性鉴别中的诊断价值。方法 回顾性分析本院2021年4月~2023年4月收治的90例肝脏局灶性病变患者的临床影像学资料。以病理结果为“金标准”。绘制受试者工作特征曲线(ROC),通过曲线比较,分析常规超声和CEUS鉴别肝内结节良、恶性的曲线下面积(AUC)值、特异度以及敏感度等。结果 ROC曲线分析发现,常规超声诊断肝脏良、恶性结节的AUC值为0.594、敏感度为40.00%、特异度为78.75%;CEUS诊断肝脏良、恶性结节的AUC值为0.856、敏感度为80.00%、特异度为91.25%,CEUS诊断AUC值显著高于常规超声诊断(P<0.05)。结论 CEUS对肝脏结节良恶性的鉴别效能优于常规超声,值得推广。

Objective To investigate the value of contrast-enhanced ultrasound(CEUS)in differential diagnosis of benign and malignant intrahepatic nodules.Methods The clinical imaging data of 90 patients with focal hepatic lesions admitted to the hospital between April 2021 and April 2023 were analyzed retrospectively.Pathological results are the"gold standard".Receiver operating characteristic curve(ROC)was plotted,and the AUC value,specificity and sensitivity of conventional ultrasound and CEUS in iden-tifying benign and malignant intrahepatic nodules were analyzed by curve comparison.Results ROC curve analysis showed that the AUC value,sensitivity and specificity were 0.594,40.00% and 78.75%in the diagnosis of benign and malignant nodules of liver by conventional ultrasound.The AUC value of CEUS in the diagnosis of benign and malignant liver nodules was 0.856,the sensitivity was 80.00%,and the specificity was 91.25%.The AUC value of CEUS diagnosis was significantly higher than that of conventional ultrasound diagnosis(P<0.05).Conclusion CEUS is more effective than conventional ultrasound in differentiating benign and malig-nant hepatic nodules,which is worth popularising.
