Abstract：Objective To investigate the value of two-dimensional ultrasound and Doppler ultrasound in the differential diagnosis of breastmasses.Methods Altogether 400 patients with breastmasses treated in our hospital from January 2013 to December 2015 were selected as research object，all patients were divided into two-Dimensional ultrasound group and Doppler ultrasound group according to the different diagnosismethods，two-dimensional ultrasonography and color Doppler ultrasonography were adopted respectively.Pathological diagnosis results were taken as the gold standard to determine sensitivity and specificity of two-dimensional ultrasound and Doppler ultrasound in the diagnosis ofmalignant breastmasses，positive rate，misdiagnosis rate and missed diagnosis rate were compared between two groups.Results Among 400 cases of breastmasses，133 cases were pathologically diagnosed as malignant tumors，accounting for 33.25%；267 caseswere diagnosed as benign tumors，accounting for 66.75%.The diagnostic sensitivity and specificity of two-dimensional ultrasound group in breastmalignant tumorswas 94.74%and 98.50%respectively，the diagnostic sensitivity and specificity of Doppler ultrasound group in breastmalignant tumors was 91.73%and 98.88%respectively. Peak systolic velocity（Vmax），pulsatility index（PI）and resistive index（RI）levels of Doppler ultrasonography in diagnosis of benign masses were lower than those ofmalignantmasses［（12.4±4.1）cm/s vs（28.1±5.4）cm/s，（1.1±0.1）vs（1.8± 0.2），（0.54±0.08）vs（0.81±0.10），P＜0.05］.There was no statistically significant difference between the positive rate，misdiagnosis rate and missed diagnosis rate of two groups（P＞0.05）in the diagnosis of malignant breastmass.Conclusion Two-dimensional ultrasound and Doppler ultrasound demonstrate its features of high sensitivity and specificity，and can be used effectively in the differential diagnosis of benign andmalignant breastmass through ultrasonography and blood flow characteristics.
