Diagnostic value of high-frequency color Doppler ultrasound on early breast duct carcinoma

Objective To evaluate the diagnostic value of high frequency color Doppler ultrasound on early breast duct carcinoma.Methods Thirty cases of early breast duct carcinoma(experiment group) and fifty cases of nodular hyperplasia of lobuli mammae(control group) were observed by high frequency color Doppler ultrasound.The differences of ultrasonic feature were compared.Results There was no significant difference in the number of patients with length and width ratio≥1 between two groups(P0.05).The number of patients with surrounding hyperechoic halo,irregular shape,obscure boundary,microcalcifications focus(0.04 cm) and perforating branch blood flow in experiment group was more than that in control group(P0.05).Among the ultrasonic features of early breast duct carcinoma,surrounding hyperechoic halo had the highest specificity(94%),and obscure boundary had the highest sensitivity(83%).Conclusion High frequency color Doppler ultrasound can be used to observe morphological features of breast lesions,and it is an important method for the diagnosis of early breast duct carcinoma.
