Abstract:

【Abstract】 Objective To compare the diagnostic value between acoustic radiation farce impulse(ARFI) and contrast-enhanced ultrasonography in the differential diagnosis of breast masses. Methods Forty patients with 48 masses were examined with ARFI technique and contrast-enhanced ultrasonography. The receiver operator characteristic (ROC) curves were constructed to evaluate diagnostic value with pathological result as the golden standard. Results The area of ROC curve for ARFI and contrast-enhanced ultrasonography were in 0.862 and 0.929, respectively..There was no statistically significant difference of the diagnostic values between the two methods (P.>0.05). There were also no statistically significant differences in specificity and sensitivity between the two methods (P>0.05). Conclusion The ARFI technique and contrast-enhanced ultrasonography are useful in the differential diagnosis of breast masses.

【摘要】 目的 探讨声辐射力脉冲成像与超声造影在乳腺肿物鉴别诊断中的价值。 方法 对40例女性患者共48个乳腺肿物进行超声检查,应用声辐射力脉冲成像测量肿物的剪切波速度(Acoustic radiation force impulse, ARFI),并对病灶进行超声造影检查。以病理结果作为金标准,构建受试者的工作特征曲线,比较两种方法的诊断价值。结果 ARFI技术及超声造影判断乳腺恶性病变的ROC曲线下面积分别为0.862、0.929。二者对乳腺癌诊断价值的差异没有统计学意义(P>0.05)。二者对乳腺癌诊断的敏感性及特异性之间的差异亦没有统计学意义(P>0.05)。结论 ARFI技术与超声造影有助于乳腺肿物的鉴别诊断,二者对乳腺癌的诊断价值相似。
