目的：探讨超声造影与弹性应变率比值对超声乳腺影像报告和数据系统（BI-RADS-US）检查Ⅲ～Ⅴ级乳腺肿块的诊断价值。方法169例 BI-RADS-US 诊断为Ⅲ～Ⅴ级的乳腺肿块患者术前1周分别行超声造影与弹性成像检查，分析超声造影声像图及时间-强度曲线（TIC）特征并测定弹性应变率比值，以术后病理结果为金标准，评估两种检查方法对 BI-RADS-US Ⅲ～Ⅴ级乳腺肿块诊断的灵敏度、特异度。结果超声造影与弹性应变率比值测定联合应用对于 BI-RADS-US Ⅲ～Ⅴ级乳腺肿块诊断的灵敏度、特异度及准确率分别为96．15％、94．34％及95．11％，高于采用单一方法（χ2＝4．659，P ＝0．032；χ2＝4．146，P ＝0．041）。结论超声造影与弹性应变率比值能够使 BI-RADS-US Ⅲ～Ⅴ级误判的乳腺肿块得以纠正，进一步提高乳腺良恶性病变诊断的特异度及准确率。

Objective To evaluate the value of contrast-enhanced ultrasound and ultrasonic elastography in the diagnosis of breast lesions with BI -RADS Ⅲ -Ⅴ.Methods 169 patients with BI -RADS Ⅲ -Ⅴ breast lesions were underwent contrast -enhanced ultrasound and ultrasonic elastography 1 week before surgery.Pathological findings were used as the gold standard to evaluate the diagnostic accuracy of contrast -enhanced ultrasound and ultrasonic elastography in diagnosis of BI -RADS Ⅲ -Ⅴ breast lesions.Results The combination of contrast -enhanced ultrasound and ultrasonic elastography in diagnosis of BI -RADS Ⅲ -Ⅴ breast lesions,with the sensitivi-ty,specificity and accuracy of 96.15%,94.34%,and 95.11%,respectively.The difference was statistical signifi-cance compared with single method(χ2 =4.659,P =0.032,χ2 =4.146,P =0.041).Conclusion The combination of contrast -enhanced ultrasound and ultrasonic elastography improves the diagnostic accuracy of Ⅲ-Ⅴ breast lesions.
