ABSTRACT

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.
