高频彩色多普勒超声检查对乳腺癌的早期诊断价值

目的 探讨高频彩色多普勒超声检查在乳腺癌早期诊断中的价值.方法 回顾性分析46例经手术后病理证实为乳腺癌的术前高频彩色多普勒超声诊断资料.结果 术前超声诊断乳腺癌41例,纤维腺瘤5例,超声诊断与病理符合率为89.1%.乳腺癌的二维声像图特征：肿块形态欠规则,无包膜,边界欠清,部分呈毛刺状或蟹足样,纵横比≥1,内部为不均匀弱回声,部分见砂粒样钙化灶,后方回声衰减;彩色多普勒血流特征：肿块周围及内部可见血流信号,Vmax值范围：6.6～45.1 cm/s;Vmean（21.50±10.62）cm/s;阻力指数（RI）：0.59～1.0,平均（0.74±0.10）.结论 高频彩色多普勒超声检查对乳腺癌的早期诊断具有很高的价值.

Value of high-frequency color doppler ultrasound in the diagnosis of early breast cancer

Objective To explore the value of high-frequency color Doppler ultrasound in the early diagnosis of breast cancer. Methods 46 cases of pathologically confirmed by surgery for breast cancer after preoperative high-frequency color Doppler ultrasound diagnosis were retrospectively analyzed. Results Among preoperative ultrasound diagnosis of breast cancer(41 cases) ,5 cases was fibroadenoma and ultrasound diagnosis and pathology diagnosis consistent rate was 89. 1%. Two-dimensional sonographic features of breast cancer were lumps form less rules,no capsule, the border less clear,and some was like or Crab-like glitches,and Aspect ratio was greater than 1,internal had the non-uniform weak echo,some showed the sand-like calcification,rear echo attenuation,Color Doppler flow characteristics :mass flow signals could be seen around and inside, Vmax value range was 6. 6 cm / s ～ 45. 1 cm / s, Vmean(21.50 ± 10.62) cm/s,RI:0.59 ～ 1.0,an average of(0.74 ±0.1). Conclusion High frequency color Doppler ultrasonography in early diagnosis of breast cancer had a high value.
