Investigate the application value of color Doppler ultrasound in differential of breast mass

Objective To investigate the clinical value in differential diagnosis of benign and malignant breast mass.Methods One hundred and eighty three breast mass patients confirmed by pahthology,including 68 benign cases and 115 malignant cases,were retrospectively analyzed.The sonogram and blood flow of the mass were compratively analyzed.The blood flow parameter RI which detected by pulse wave Doppler were also compratively analyzed.Results Shapes,margins,posterior attenuation,L/T ratio,and microcalcification showed the significant differences between benign and malignant mass patients(P0.05).RI0.7 were in the malignant mass.Lymphadenectasis were found in 38 malignant caeses,and lymph node reactive hyperplasia were found in the 9 benign patients.Conclusion Color Doppler ultrasound can differentiate benign and malignant breast mass,it has important value in clinical application.
