摘要
目的探讨常规超声结合超声造影(CEUS)和弹性成像(UE)对提高小肝癌检出率的诊断价值。方法常规超声、CEUS、UE三者结合进行超声评价,以病理结果作为金标准,比较3种方法对肝硬化和小肝癌的鉴别诊断价值。结果常规超声、UE、CEUS诊断肝癌的敏感性、特异性、准确性,三者之间的差异具有统计学意义(P<0.05),UE对于超声造影诊断不确定的病灶诊断准确率为75%。结论 CEUS对肝硬化结节和肝癌鉴别诊断的价值较UE更大,UE对于CEUS无法明确诊断的病灶有补充作用。常规超声、CEUS、UE三者结合,降低了对小肝癌的漏诊及误诊率。
Objective To explore the diagnostic value of contrast-enhanced ultrasound （CEUS） and uhrasonic elastogra- phy （UE） in differentiating benign and malignant hepatic lesions. Methods Conventional uhrasonography, UE and CEUS were performed on each patient. The golden standard came from the clinical follow-up and pathological results. The diagnostic performances of the three methods were evaluated with the interobserver agreement. Results The sensi- tivity, specificity and the accuracy of conventional uhrasonography for diagnosing malignant hepatic tumors compared with UE and CEUS, had significant differences （P 〈 0.05）. Lesions without certain diagnosis by CEUS estimated by UE with an accuracy of 75%. Conclusion CEUS has more diagnostic value than UE in differentiating benign and malignant liver lesions. UE shows supplementary effect when CEUS fails to clarify a diagnosis. It can ensure the number of le- sions, also it can discover the atypical lesion range.
