Objective：To evaluate the clinical application of ultrasound diagnosis for breast neoplasm.
Methods：The ultrasound examination in 137 cases with pathologically proved breast neoplasm was done and the clinical data were retrospectively analyzed.
Results：The main sonogram of breast neoplasm showed hypoechoic masses. The benign and malignant breast tumors were significantly different in shape, boundary, capsules, rear echo, detection rates of minute calcification and blood flow display rates (P＜0.05). The ultrasonographic characteristics of axillary metastatic lymph node were enlarged and low internal-echo.
Conclusions：The preoperative diagnosis rate of breast neoplasm can be improved by color Doppler flow imaging on the basis of two dimensional ultrasonography combined with axillary lymph node examination.
