【摘要】：目的:探讨超声实时剪切波弹性成像(SWE)与实时组织弹性成像(RTE)对早期乳腺癌的鉴别诊断价值。方法:SWE与RTE技术鉴别诊断127例乳腺病灶,以手术病理结果作为金标准。分析两种技术对乳腺癌的诊断效能:误诊及漏诊例数、符合率、诊断的ROC曲线下面积、敏感度、特异度、阴性预测值与阳性预测值。结果:与病理结果比较:SWE漏诊6例,误诊7例,RTE漏诊3例,误诊5例,诊断符合率分别为89.76%、93.70%,SWE与RTE诊断的ROC曲线下面积分别为0.947与0.980,SWE与RTE对乳腺癌诊断的指标分别为:灵敏度为86.96%、93.48%;特异度为91.36%、93.83%;阳性预测值为85.11%、89.58%;阴性预测值为92.5%、96.20%,RTE优于SWE。结论:SWE与RTE对早期乳腺癌的鉴别诊断均具有较高价值,但RTE对早期乳腺癌的诊断价值更优于SWE。
[Abstract]:Objective: to study the real time shear wave elastic imaging (SWE) and the real time tissue elastic imaging (RTE). Methods the differential diagnosis of breast lesions in 127 cases was performed by using the technique of: SWE and RTE. The diagnostic efficacy of the two techniques for breast cancer was analyzed: the number of misdiagnosis and missed diagnosis, the coincidence rate, the area under the ROC curve, the sensitivity and specificity of the two techniques. Results: compared with the pathological results, 6 cases were missed diagnosis, 3 cases were misdiagnosed in 7 cases and 5 cases were misdiagnosed. The diagnostic coincidence rate was 89.76% respectively. The area under the ROC curve diagnosed by SWE and RTE were 0.947 and 0.980, respectively. The diagnostic indexes of SWE and RTE for breast cancer were as follows: the sensitivity was 86.96 and 93.48; The specificity was 91.36 and 93.83; The positive predictive value was 85.110.89.58; The negative predictive value of 92.5% and 96.20% RTE was superior to that of SWE.Conclusion both RTE and WSWE are of high value in the differential diagnosis of early breast cancer. But the value of RTE in the diagnosis of early breast cancer is better than that of SWE.

【正文快照】： 乳腺癌的死亡率位居女性肿瘤前列,早期诊断和早期治疗可明显改善患者的预后[1],乳腺癌的早期表现不典型,主要是患乳出现无痛、单发的小结节,常被误诊或漏诊,超声弹性成像是一种体外测定组织机械特设的超声检查方法,可获得一般常规成像模态所无法获取的组织弹性信息[2],研究[3]
