摘　　要：目的探讨超声弹性成像(UE)应变率比值法对浆细胞性乳腺炎与乳腺癌的鉴别诊断价值。方法对我院病理诊断为浆细胞性乳腺炎41例及乳腺癌76例的患者行超声弹性成像的应变率比值分析,应用ROC曲线分析此方法鉴别诊断浆细胞性乳腺炎与乳腺癌的灵敏度与特异度。结果浆细胞性乳腺炎和乳腺癌的弹性应变率比值的平均值分别为4.20±0.65、5.45±0.76,两者的应变率比值差异具有统计学意义(P<0.05),ROC曲线显示,以阈值为4.88时鉴别浆细胞性乳腺炎与乳腺癌的灵敏度、特异度及准确度分别为93.1%、90.2%和85.7%,ROC曲线下的面积为0.935±0.024。结论弹性应变率比值法对浆细胞性乳腺炎及乳腺癌的鉴别诊断具有重要价值。Objective To investigate the value in diagnosis of plasma cell mastitis and breast cancer with the method of the mean strain ratio of real-time ultrasound elastography （UE）. Methods The analysis of the strain ratio of UE score was used to 41 cases of plasma cell mastitis and 76 cases of breast cell. The sensitivity and specificity of this method were assessed by ROC curve analysis. Results The average value of the strain ratio of UE of the plasma cell mastitis and breast cancer were, respectively, 4.20±0.65 and 5.45±0.76. Moreover, there was significant difference（P〈0.05）. When the cut-off value was 4.88, plasma cell mastitis and breast cancer were differentiated. And sensitivity, specificity and accuracy were 93.1%, 90.2% and 85.7% respectively. It gave an area under the curve of 0. 935±0. 024. Conclusions Real time tissue elastography is highly valuable for the diagnosis and differential diagnosis of plasma cell mastitis and breast cancer.
