【摘要】 目的探讨乳腺肿块的高频彩超表现及与触诊径值之间的相关性在评判良恶性病变中的价值。方法回顾资料完整的79个乳腺肿块(良性46,恶性33)的高频彩超特征,并分析比较二维测值与触诊径值之间的差异程度在良恶性乳腺病变中的不同。结果乳腺良恶性病变不仅边界、形态、后方衰减、血流信号分级和阻力指数存在明显差异,触诊径值与二维测值之间的差异程度在良恶性组之间也有统计学意义(P>0.05)。结论触诊径值大于二维测值是乳腺恶性病变的另一重要特征,与高频彩超结合有助于乳腺良恶性病变的鉴别。更多还原

【Abstract】 Objective To evaluate the diagnostic value of signs of high-frequency color doppler ultrasound and diameter of palpation for differentiating benign and malignant breast tumors.Methods Breast lesions in 79 patients(46 cases benign tumors,33 cases malignant tumors)were observed in terms of high frequency ultrasonographic features,then the measurement of two-dimensional sonogram and palpation in breast benign and malignant tumors were compared retrospectively.Results There was difference in measurement,shape,edge,rear attenuation,calcifications,blood flow grade and resistance index between malignant and benign breast tumors.There were significant difference in measurement of two-dimensional sonogram and palpation between group benign and malignant tumors(P>0.05).Conclusion Diameter of palpation larger than the size of two-dimensional sonogram is another important feature of malignant change.Signs of high-frequency color doppler ultrasound and size of palpation and two-dimensional sonogram are valuable in identifying benign and malignant breast tumors.更多还原
