Abstract: 【Abstract】 Objective〓To investigate the method of combination of ultrasound elastography and conventional ultrasonography for differentiating benign and malignant hepatic tumors. Methods Comprehensive creteria consisting of diameter, echogenicity, elastic score and strain of hepatic tumors was established for distinguishing benign and malignant hepatic tumors. Results Comprehensive creteria for diagnosis bear a sensitivity of 87.9%, a specificity of 97.8% and an accuracy of 93.9%, higher than that of other valuables (P<0.05). Conclusion It may be probable to differentiate benign and malignant tumors more accurately and objectively by the integrated combination of ultrasound elastography and conventional ultrasonography.

摘要： 【摘要】 目的 探讨超声弹性成像与常规超声相结合用于诊断肝脏良恶性病灶的具体方法。方法〓依据病灶大小、回声强度、弹性评分及应变值数据对病灶良恶性进行综合判定。结果〓最终诊断结果鉴别肝良恶性病灶的敏感性为87.9%、特异性为97.8%、准确性为93.9%,与单独采用SR值、应变值A、应变值B、病灶大小及回声强度等诊断指标相比,诊断敏感性、特异性及准确性均有显著性提高(P<0.05)。结论〓超声弹性成像与常规超声相结合用于诊断肝脏良恶性病灶可能成为一种较客观、准确而便捷的方法。
