摘　　要：目的:对比研究超声弹性应变率比值法与评分法鉴别乳腺结节良恶性的应用价值。方法:选择2013年6月至2014年3月72例乳腺结节患者的78处病灶进行超声弹性成像检查,测量其应变率比值并进行弹性评分,构建受试者工作特征(ROC)曲线,以病理诊断结果作为金标准,对结果进行整理分析。结果:超声弹性应变率比值的曲线下面积为0.925,灵敏度、特异度是92.50%、92.11%,弹性评分法的曲线下面积是0.891,灵敏度、特异度是85.00%、89.47%。两者联合的灵敏度、特异度分别为95.00%、94.74%,高于单独任何一种方法。结论:超声弹性应变率比值是一个定量指标,能客观反映乳腺病灶的硬度情况,鉴别诊断价值高于弹性评分法,但两者联合诊断价值最高。Objective： To compare the differential diagnosis value of strain rate ratio and elasticity score in benign and malignant breast nodules. Methods： 78 lesions of 72 patients selected from our hospital during the period from June 2013 to March 2014 were given ultrasound elastography examination,measured the strain rate ratio and elasticity score,we drew the receiver operating characteristic（ ROC） curve. The pathological diagnosis as the gold standard,the results were analyzed. Results： The area under the ROC curve of strain rate ratio was 0. 925,the sensitivity and specificity were 92. 50%,92. 11%. The area of elasticity score was 0. 891,the sensitivity and specificity were 85. 00%,89. 47%. Combined the two diagnosis the sensitivity and specificity were 95. 00%,94. 74%. The method of their correlation was higher than that of only single obviously. Conclusion： Ultrasound elastic strain rate ratio is a quantitative indicator,is more objective,can reflect the hardness of breast lesions,the value of differential diagnosis is higher than the elasticity score,both unite has the highest diagnostic value.
