超声造影对肝内高回声病变的鉴别诊断价值

摘要

Objective To assess the value of contrast-enhanced ultrasound(US)in differential diagnosis of hyperechoic hepatic lesions when compared to conventional US.Methods Eighty-four hyperechoic liver lesions in 66 patients were examined using both conventional and contrast-enhanced US techniques.Results Receiver operating characteristic analysis revealed a significant improvement in the discrimination of malignant versus benign hyperechoic hepatic lesions (area under the receiver operating characteristic curve,0.867±0.045 at conventional US,0.997±0.003 with contrast-enhanced US(P＜0.0001).For correct diagnoses types of hyperechoic liver lesions,contrast-enhanced US improved from 64.3% to 92.9%,comic)ared with conventional US (P＜0.001).Conclusions Contrast-enhanced US showed a significant improvement in characterization and differentiation of hyperechoic hepatic lesions when compared to conventional US.%目的 探讨超声造影对肝内高回声病变的诊断价值.方法 应用常规超声与超声造影检查66例84个肝内高回声病变.结果 对于鉴别良恶性诊断,经ROC曲线分析,常规超声曲线下面积0.867±0.045,超声造影曲线下面积0.997±0.003,超声造影提高了诊断效能(P＜0.0001).常规超声对病灶类型正确诊断率为64.3%,超声造影正确诊断率为92.9%.结论 超声造影提高了对肝内高回声病变的鉴别诊断水平.
