【摘要】：目的 :探讨超声弹性成像技术在乳腺实性肿块诊断中的应用价值。方法 :回顾性分析已行常规超声检查和弹性成像检查的154个乳腺肿物,以病理诊断为金标准,构建受试者应用工作特征曲线(ROC),观察弹性成像在乳腺实性肿块诊断中的应用价值。结果:常规超声、弹性评分的曲线下面积(AUC)分别为0.865、0.868,差异无统计学意义。弹性应变率比值为1.7时诊断乳腺恶性肿块的敏感性76.79%,特异性87.76%,AUC为0.857。结论:弹性成像技术在乳腺实性肿块的诊断中具有一定的应用价值,可作为常规超声的辅助诊断。弹性比值作为客观的超声诊断方法,在临床上具有广泛的应用前景。
[Abstract]:Objective: to evaluate the value of ultrasonic elastography in the diagnosis of solid breast masses. Methods: 154 breast masses which had been examined by conventional ultrasound and elastic imaging were analyzed retrospectively, and pathological diagnosis was regarded as the gold standard. In order to observe the value of elastic imaging in the diagnosis of solid breast masses, we constructed the operating characteristic curve and observed the value of elastic imaging in the diagnosis of solid breast masses. The area under the curve of elastic score was 0.865 卤0.868, the difference was not statistically significant. The sensitivity of elastic strain rate ratio was 1.7 and the specificity of AUC was 0.8577.Conclusion: elastic imaging technique can be used in the diagnosis of breast masses with a sensitivity of 76.79 and a specificity of 87.76 with AUC of 0.857. It has certain application value in diagnosis. It can be used as assistant diagnosis of conventional ultrasound and elastic ratio as objective ultrasonic diagnosis method, which has a wide application prospect in clinic.
