【摘要】：目的探讨超声弹性成像(UE)在BI-RADS 4A类乳腺肿块良恶性鉴别诊断中的应用价值。方法回顾性分析229例BI-RADS 4A类乳腺肿块患者的UE资料。结合病理分析弹性评分、病灶内最硬部分的弹性应变率比值R_1及病灶边缘最硬部分的弹性应变率比值R_2在良恶性肿块中的差别。构建R_1、R_2的ROC曲线。比较弹性评分、R_1、R_2单独使用或联合使用时的灵敏度、特异度及准确度之间的差异。结果恶性肿块的弹性评分、R_1及R_2均高于良性肿块(P0.001)。R_1、R_2最佳截断点分别为2.5、2.02。R_2的灵敏度(100%)最高(P0.05),弹性评分与R_2联合的特异度(91.8%)、准确度(90.8%)最高(P0.05)。结论 UE在4A类乳腺肿块的良恶性诊断方面有较高临床价值。当弹性评分与R_2联合使用时可提高4A类乳腺肿块诊断特异度及准确度。
[Abstract]:Objective to evaluate the value of ultrasonic elastography in differential diagnosis of benign and malignant breast masses of BI-RADS 4A.Methods the UE data of 229 patients with BI-RADS 4A breast mass were retrospectively analyzed.According to the elastic score of pathological analysis, the difference of elastic strain rate ratio between the hardest part of the lesion and the ratio of elastic strain rate of the hardest part of the lesion and the ratio of elastic strain rate of the hardest part of the lesion to that of the lesion was found in benign and malignant tumors.Construct the ROC curve of R1 / R2.To compare the difference of sensitivity, specificity and accuracy between R1 / R _ 2 and R1C _ 2 when used alone or in combination.Results the elastic scores of Rast1 and R2 were higher than those of benign tumors (P 0.001N. R1C / R2). The best cut-off point of RSP was 2.5 + 2.02.R2. The sensitivity of R2 was 100). The maximum of P0.05 and the specificity of elasticity score combined with R2 were 91.8% and 90.8%, respectively (P 0.05).Conclusion UE has high clinical value in the diagnosis of benign and malignant breast masses.The diagnostic specificity and accuracy of 4A breast masses can be improved by using elastic score combined with RSP 2.
