Value of high frequency color Doppler ultrasonography in the diagnosis of breast cancers

Objective To investigate the value of high frequency color Doppler ultrasonography in the diagnosis of breast cancers. Methods A total of 108 patients with 113 breast tumors confirmed by operation and pathology were examined with high frequency color Doppler ultrasonography.The features including tumor shape,margin,inner echogenicity,calcification,acoustic attenuation,and color flow signals and Doppler waveform on color Doppler ultrasonography were analyzed retrospectively.Results Among 113 breast tumors in 108 patients,ultrasonography diagnosed 80 tumors as breast cancer,suspected 17 tumors as cancer,misdiagnosed 12 tumors and missed 4 tumors preoperatively.The diagnostic accuracy for ultrasonography was 88.9%(96/108).Color Doppler ultrasonography showed color flow signals inside and around the lesions in 53 tumors and penetrating flow signals in 4 tumors.The peak systolic velocity was(0.11±0.08m/s, and RI was 0.87±0.09.Conclusion High frequency gray scale and color Doppler ultrasonography are valuable in improving the diagnostic accuracy for breast cancers.
