超声弹性成像对乳腺实质性肿瘤定性诊断价值

目的探讨超声弹性成像对乳腺实性肿瘤定性诊断的价值。方法采用灰阶超声和弹性成像对35例（共39个病灶）乳腺肿瘤患者进行检查,并在弹性成像模式下对所有病灶的硬度进行半定量分析;分别在弹性模式和灰阶超声下测量病灶面积,计算二者比值,并与病理结果对照分析。结果乳腺癌组病灶平均硬度评分大于纤维腺瘤组（P〈0.01）;乳腺癌组两种成像模式下的病灶面积比大于纤维腺瘤组（P〈0.01）。结论超声弹性成像对乳腺肿瘤的良恶性鉴别有一定价值。

Value of ultrasonic elastography in qualitative diagnosis for breast parenchymatous tumors

Objective To explore the value of ultrasonic elastography in qualitative diagnosing breast parenchymatous tumors.Methods Thirty-nine breast tumors in 35 cases were scanned by gray-scale ultrasonography and elastography.The rigidity of all tumors were analyzed in elastography mode,the areas of tumors were measured in ultrasonography and elastography respectively and meanwhile the ratio was calculated.All the results were compared with the pathological types.Results Average rigidity score of focus in breast cancer group was larger than that in fibroadenomas group(P<0.01),and the area ratio of the focus in the two modes of breast cancer group was larger than that in fibroadenomas group(P<0.01).Conclusion Elastography has some value for distinguishing benign and malignant tumors of breast.
