目的：探讨超声弹性成像对乳腺肿瘤的鉴别诊断价值。方法对98例107个乳腺结节进行超声弹性成像检查，并与病理结果比较。弹性成像按5分法分级。结果107个乳腺结节，组织病理检查结果为良性结节68个，恶性结节39个。超声弹性成像评分≤3分（良性）67个结节，＞3分（恶性）40个结节。良性结节超声弹性成像与病理诊断符合率为86．8％（59／68）；恶性结节超声弹性成像与病理诊断符合率为79．5％（31／39）。以弹性成像评分＞3分，并且弹性成像病灶面积与二维超声面积比≥1．5为恶性肿瘤诊断标准，诊断乳腺恶性病变的敏感性、特异性、准确性分别为79．4％、97．1％、和90．7％。结论弹性成像可有效评估组织硬度，定量参数面积比有助于乳腺肿块良恶性的鉴别。

Objective To evaluate the value of elastosonography in the differential diagnosis of breast tumor . Methods Ninety-eight patients with 107 breast lesions were examined by elastosonography ,and the result was compare with pathological result .The grading of elastosonography was done according to 5-score evaluating method .Results The histopathological examination showed that 61 benign lesions and 39 malignant lesions in 107 breast lesions .There were 67 lesions(benign) with elastosonography score ≤3 and 40 lesions(malignant) >3.The coincidence rate of elastosonography and histopathological examination in the diagnosis of benign lesions was 86.8%(59/68),which was 79.5%(31/39) in the diagnosis of malignant lesions .Based on the diagnostic standard for malignant lesions which was the elastosonography score >3 and the ratio of lesion traced area in strain images versus in B-mode images≥1 .5 ,the sensitivity ,specificity and accuracy of elastosonograpy in the diagnosis of malignant breast lesions were 79.4%,97.1%and 90.7%,respectively. Conclusion Elastosonography can evaluate the tissue hardness effectively ,the area ratio of quantitative parameters might benefit the differential diagnosis of benign and malignant lesions .
