摘　　要：目的:探讨超声弹性成像与钙化特征在乳腺肿块良恶性鉴别诊断中的价值。方法:对90例(105个病灶)乳腺肿块女性患者的超声钙化及弹性成像特点和术后病理结果对照,对两者鉴别乳腺肿块的灵敏性、特异性和准确性进行评估。结果:以钙化特点为标准诊断乳腺肿块性质的灵敏度、特异度、准确度分别为69.4%、85.5%、80.0%;弹性成像依次分别为77.8%、94.2%、88.6%,以上指标均高于钙化特征,差异有统计学意义(P<0.05)。结论:与钙化特点相比,弹性成像在诊断乳腺肿瘤良恶性中具有更高的敏感性及特异性,可作为诊断乳腺肿瘤良恶性的重要手段。Objective： To investigate the value between ultrasonic elastography and characteristics of calcification in differential diagnosis of breast cancer and benign beast tumor. Method： Comparing characteristics of calcificationin and elastograph of 90 patients＇（ 105 lesion） breast lumps,and comparing the postoperative pathological results,then evaluating the differential diagnostic effects on breast lumps of both methods. Results： The sensitivity,specificity and accuracy of characteristics of calcification used as the standard for the diagnosis of beast lump were 69. 4%,85. 5%,80. 0%; while that of elastography in diagnosis of breast lump were 77. 8%,94. 2%,88. 6%,which is significantly higher than characteristics of calcification. Differences of both methods showed statistical significance（ P 0. 05）. Conclusion： Compared with the characteristics of calcification,elastograph has higher sensitivity,specificity,which can be regarded as an important diagnostic measure in differentiating beast cancer and beast benign tumor. It is worth of clinical promotion and application.
