目的探讨小乳腺癌(≤2 cm)的高频声像图及彩色多普勒血流特征,评估彩超对小乳腺癌的诊断价值。方法对经病理证实的67例乳腺小肿块高频声像图及彩色多普勒血流特征进行回顾性分析,与病理结果对照。结果小乳腺癌的高频声像图仅具备部分恶性特征,其中肿块内微小钙化是其重要特征,另外脉冲多普勒(PD)频谱阻力指数RI≥0.70及彩色多普勒血流显像(CDFI)的血流分级≥T2级亦具有很好的阳性预告意义。结论使用高频二维超声结合彩色多普勒超声可提高小乳腺癌的术前诊断准确率。
Objective To evaluate the diagnostic value of color Doppler ultrasonography in the diagnosis of small breast cancer by high frequency ultrasonography and color Doppler flow imaging of small breast cancer (≤2 cm). Methods Retrospective analysis of 67 cases of small breast masses confirmed by pathology and color Doppler flow characteristics were compared with pathological results. Results High-frequency ultrasonography of small breast cancer only had some malignant features. Micro-calcification in the mass was an important feature. In addition, the resistance index of pulse doppler (PD) RI≥0.70 and color Doppler flow imaging (CDFI) Blood flow grade ≥ T2 level also has a good positive predictive significance. Conclusion High-frequency two-dimensional ultrasound combined with color Doppler ultrasound can improve the accuracy of preoperative diagnosis of small breast cancer.
