摘要
目的探讨超声弹性成像在乳腺良恶性病变鉴别诊断中的应用价值.方法对20例乳腺疾病患者的37个病灶的弹性成像图与手术后病理及随访结果进行分析.结果超声弹性成像评分1-3分多为良性病变,4-5分多为恶性病变.以弹性评分≥4分诊断乳腺恶性病变、弹性评分<4分诊断乳腺良性病变,敏感性100%,特异性93.10%,准确度94.59%.弹性应变率比值(strain ratio,SR)在良恶性病变组间有统计学意义(P<0.05).结论超声弹性成像在乳腺良恶性病变鉴别诊断中结合二维及彩色多普勒显像可提高恶性病变诊断的敏感性、特异性和正确性,具有较高的应用价值.
Objective To probe the application value of elastosonography in differentiating diagnosis of benign and malignant breast tumors.Method Elastography was conducted on 20 patients with 37 breast lesions to differentiate benign tumors from maglinant tumors,and the results were compared with those by pathology after operation.Results Most of benign tumors' scores of elastography were 1-3,and most of malignant tumors' scores were 4-5.Accuracy of elastography in differentiating breast malignant tumors was 94.59%,while the sensitivity was 100%,the specificity was 93.10%.There was a statistically significant difference between two benign tumors' SR and malignant tumors' SR.Conclusions Combined to 2D and CDFI,elastography can improve the accuracy,sencitivity and specificity of differentiating diagnosis in breast benign and malignant tumors,and it has a higher application value.
