摘要
目的探讨高频彩超在小乳腺癌中的诊断价值。方法对经手术病理证实的41例小乳腺癌(直径≤2 cm)的高频二维声像图及彩超特点进行回顾分析。结果小乳腺癌的二维声像图特点大多属于不典型,少数表现为典型恶性特征;能量多普勒显示以Ⅱ～Ⅲ级血流为主,血流形态包括穿入性血流、分叉血流与束状血流等;脉冲多普勒频谱阻力指数>0.7,也具有很好的阳性预告意义。结论使用高频二维超声结合能量多普勒血流特点及频谱多普勒可以提高小乳腺癌的定性诊断。
Objective To explore the value of high-frequency color Doppler in the diagnosis of small breast cancer.Methods Features of high-frequency two-dimensional ultrasonograph and color ultrasonograph of 41 patients with small breast cancer proven by postoperative pathological exam were analyzed retrospectively.Results Images of the two-dimensional ultrasonograph of small breast cancer were mostly atypical and just a few patients were shown typical malignant features.Powered Doppler detected most small breast cancer of grade II or III blood stream,which included penetration type,ramify type,and bind type.The pulse Doppler resistance index of 0.7 or higher had reasonable value in predicting breast cancer.Conclusion High-frequency ultrasonography combined with powered Doppler imaging and spectra Doppler can improve the qualitative diagnosis of the small breast cancer.
