组织弹性成像鉴别乳腺良恶性肿块的价值评估

目的评价组织弹性成像技术在鉴别诊断乳腺良恶性肿块中的价值.方法用组织弹性成像技术对175名患者的184个乳腺肿块进行良恶性的鉴别诊断,并与术后的病理结果进行对照.结果组织弹性成像技术对乳腺肿块的良恶性鉴别诊断准确性、灵敏度和特异度分别为78.8%(145/184),76.1%(51/67)和80.3%(94/117).结论组织弹性成像为超声鉴别诊断良恶性乳腺肿块提供了一个新的手段.尽管可能会增加一定数量的假阳性,但更重要的是弹性成像能有效地减少假阴性的发生.

Evaluation of elastography application in differentiating benign and malignant breast tumors

Objective To evaluate the value of elastography in differentiating benign and malignant breast tumors.Methods Elastography was performed on 175 patients with 184 breast tumors to differentiate benign tumors from malignant ones.Results of elastography were compared with post-operative pathological results.Results Accuracy of elastography in differentiating breast tumors was 78.8%(145/184),while the sensitivity was 76.1%(51/67),the specificity was 80.3%(94/117).Conclusion Elastography is a newly valuable technique of ultrasonography in differentiating benign and malignant breast tumors.It is important to know that elastography can efficiently decrease cases of false-negative,even though some cases of false-positive may be increased.
