高频超声及彩色多普勒对乳腺癌的诊断价值

目的:探讨高频超声及彩色多普勒对乳腺肿块定性诊断的价值。方法:利用高频二维超声对365例乳腺肿块患者进行检查,观察肿块的部位、大小、形态、边界、纵横比、内部回声、后方回声、有无微小钙化及腋下淋巴结肿大等,结合彩色多普勒血流显像及阻力指数(RI)最大峰值流速(Vmax)观察乳腺肿块的特征。结果:365例乳腺癌均经手术及病理证实,超声诊断提示恶性肿瘤339例,诊断符合率92.88%,误诊26例占17.22%。结论:高频二维超声结合彩色多普勒血流显像对乳腺癌具有较高的诊断价值。

Diagnostic value of high-frequency ultrasound and color Doppler ultrasound on breast cancer

Objective:To explore the values of high-frequency ultrasound and color Doppler ultrasound in the qualitative diagnosis of breast lumps.Methods:365 patients with breast lumps were examined by high-frequency two dimensional ultrasound to observe the location,form,border,longitude-latitude ratio,inner and behind echo,tiny calcification points and the axillary lymphonodus.All the patients were examined by color Doppler ultrasound to observe the characters of breast lumps by color Doppler flow imaging,resistance index(RI) and peak systolic velocity(Vmax).Results:365 patients with breast lumps accepted operation therapy and had pathologic diagnosis,339 patients was diagnosed as breast cancer by ultrasound,the coincidence rate was 92.88%,and the misdiagnosis rate was 17.22%(26 patients).Conclusion:High frequency two dimensional ultrasound combined with color Doppler flow imaging are of value in the diagnosis of breast cancer.
