Objective To evaluate the diagnostic value of color Doppler ultrasound between benign and malignant breast tumors.Methods Ninety-five patients with breast tumors were screened with two-dimensional ultrasound firstly,then color Doppler flow imaging (CDFI).The distribution of the tumor blood vessels was recorded and inspected with pulsed wave Doppler (PWD) to identify the highest peak systolic velocity (PSV),resistant index (RI) and pulsitile index (PI).SPSS 10.0 software was used to analyse data with chi-squire test and t test.Results (1)In all of 95 recruited patients,93 patients were found with breast tumors via ultrasonography;(2)There was significant difference in the Adler grade of blood flow between the benign and malignant tumors;(3)The hemodynamic parameters showed that PSV,PI,RI,Vmean were significantly higher in the malignant lesions than those in the benign ones.Conclusions (1)Ultrasonography is served as an accurate,convenient and noninvasive method to detect the breast tumors;(2)Via comprehensive analysis and evaluation of the parameters of blood flow grade,PSV,Vmean,PI and RI,CDFI may play a very important role to differentiate the breast tumors between benign and malignant ones.
