摘要

目的探讨加速时间指数（ATI）及弹性应变率比值（SR）鉴别诊断乳腺良恶性肿瘤的应用价值。方法回顾性分析120例乳腺肿瘤患者的临床资料

根据病理结果分为良性组76例（98个病灶）和恶性组44例（57个病灶）

均行常规超声和超声弹性成像检查

计算并比较两组二维超声图像特征、ATI及SR值。绘制受试者工作特征（ROC）曲线分析ATI、SR值及其联合鉴别诊断乳腺恶性肿瘤的价值

计算曲线下面积（AUC）。结果良、恶性组二维超声图像特征（病灶形态、长轴方向、回声强度、内部回声是否均匀、边界情况、钙化程度、后方回声强度）比较

差异均有统计学意义（均P<0.05）;恶性组ATI、SR值均高于良性组（0.18±0.05 vs. 0.11±0.03

3.05±0.65 vs. 2.33±0.41）

差异均有统计学意义（均P<0.05）。ROC曲线分析显示

ATI、SR值鉴别诊断乳腺恶性肿瘤的AUC分别为0.842、0.813

且联合应用的AUC（0.906）高于其单独应用（均P<0.05）。结论 ATI、SR值均能准确鉴别乳腺良、恶性肿瘤

两者联合应用价值更高。

Abstract

Objective To explore the application value of acceleration time index（ATI）and ratio of elastic strain rate（SR）in the differential diagnosis of benign and malignant breast tumors.Methods The clinical data of 120 breast tumor patients was analyzed retrospectively.They were divided into benign group（76 cases

98 lesions）and malignant group（44 cases

57 lesions） according to the results of pathological examination. All patients were underwent conventional ultrasound and ultrasound elastography

the ATI and SR values of the two groups were calculated and compared. The receiver operating characteristic（ROC）curve was drawn to analyze the value of ATI

SR and their combination in the differential diagnosis of malignant breast tumors

the area under the curve（AUC） was calculated.Results Two-dimensional ultrasound image characteristics（lesions form

long axis direction

echo intensity

internal echo uniformity

boundary condition

calcification degree

posterior echo intensity）were compared between the two groups

the differences were statistically significant（all P<0.05）.The ATI and SR values of patients in the malignant group were significantly higher than those in the benign group（0.18±0.05 vs. 0.11±0.03

3.05±0.65 vs. 2.33±0.41）

the differences were statistically significant（both P<0.05）.ROC curve analysis showed that the AUC of ATI and SR values for differential diagnosis of malignant breast tumors were 0.842 and 0.813

respectively

and the AUC（0.906）of the combined application was higher than that of the single application（both P<0.05）.Conclusion Both the acceleration time index and SR show good application value in the differential diagnosis of benign and malignant breast tumors

and the combined value of the two is higher.
