Color Doppler two-dimensional ultrasound combined with real-time ultrasonic shear wave elastography in breast cancer diagnosis / 国际生物医学工程杂志

ABSTRACT

Objective To evaluate the value of color Doppler two-dimensional ultrasound combined with real-time ultrasonic shear wave elastography (SWE) in the early diagnosis of breast cancer.Methods A total of 110 suspected breast tumor patients from October 2015 to April 2017 were selected as subjects.Comprehensive detailed examinations on the patients were conducted by routine two-dimensional ultrasound,color Doppler and SWE,and the lesion location,size,boundary,capsule,internal echo,blood flow,elastic value and other related data were recorded.The BI-RADS classification was conducted based on these data.Pathological diagnosis was used as the gold standard to compare the diagnostic effects of color Doppler two-dimensional ultrasound and the combination of color Doppler two-dimensional ultrasound and SWE.Results Of the 110 patients,78 were malignant and 32 were benign.The sensitivity of color Doppler two-dimensional ultrasound for breast cancer diagnosis was 83.3％,the specificity was 81.2％,and the accuracy was 82.7％.The sensitivity of color Doppler two-dimensional ultrasound combined with SWE for breast cancer diagnosis was 88.5％,the specificity was 90.6％,and the accuracy was 94.5％.Conclusion Color Doppler two-dimensional ultrasound combined with SWE can complement each other and improve the qualitative and quantitative diagnosis of early breast cancer.
