The value of diagnosis of breast cancer by strain ratio(SR) of real-time tissue elastography technology
Abstract：Objective To explore the value of diagnosis of breast cancer by strain ratio( SR) of real-time tis-sue elastography technology.Methods Sixty-two breast lesions in 51 female patients were examined with convention-al ultrasonic before operation and pathological biopsy, The lesions were graded according to the breast imaging repor-ting and data system ( BI-RADS ) .Real-time tissue elastography technology was performed to diagnose the breast cancer.The accuracy of the conventional ultrasonic and SR were compared.Results The sensitivity, specificity,and accuracy of SR were 94.4%( 34/36 ) , 92.3%( 24/26 ) , and 93.5%( 58/62 ); weighted Kappa was 0.892; AUC was 0.864 ( 95%CI 0.801 ~0.943 ) .The sensitivity, specificity, and accuracy of conventional ultrasonic were 89.1%(33/37), 88.0%(22/25), and 88.7%(55/62) respectively.weighted kappa was 0.881 and AUC value was 0.830(95%CI 0.791~0.912).The accuracy of SR was higher than that of the convertional ultrasonic(P<0.05 ) .Conclusion The accuracy of SR of real-time tissue elastography technology is superior to the conventional ul-trasound in the diagnosis of breast malignant lesions.
