Diagnostic value of color Doppler ultrasonography combined with mammography on breast cancer

Abstract

Objective To investigate the value of high frequency 2-Dimensional and color Doppler flow imaging combined with mammography on the diagnosis of breast cancer. Methods 90 patients with breast cancer and benign breast lesions in 22 cases, respectively, separate by color Doppler ultrasound and mammography and their combination were compared. Results The blood flow signals were Ⅱ～Ⅲ grade(76.32% ) in breast cancer and benign breast lesions less blood flow to 0 ～Ⅰ grade ( 87.10% ); The detection rate of blood flow 89.48% in breast cancer were significantly higher than 38.71% in benign breast lesions ( x2 = 4.57, P ＜ 0. 05 ); 68 cases (75.5 % ) were diagnosed by mammography 38 cases(55.8% ) in diameter≤2. 0em were significantly higher than 30 cases(44.4% ) in ≤ 1.0 cm( x2 = 3.97, P ＜ 0. 05 ); The corresponding rate of Joint Inspection 85.7 % (96/112) was higher than the r 72.3% (81/112) in color Doppler ultrasound and 75.8% (85/112) in mammography ( x2 = 3.87, x2 = 3.85, all P ＜0. 05 ). Conclusion Color ultrasonography combined with mammography could raise diagnostic rate of breast cancer.Their combination is the best one of breast imaging examinations.
