Objective To explore the diagnostic value of ultrasound elastography

stiff ring sign and histogram analysis for benign and malignant breast masses.Methods A total of 59 breast masses which confirmed by clinic and pathology were selected

they were exancined by converctional routine ultrasound and elastography

and the threshold was adjusted on the elastography image to show their stiff ring signs

histogram analysis was used.The receiver operating characteristic（ROC） curve was drawn

the elastography

elastography combined with stiff ring sign and histogram analysis were compared to evaluate the diagnostic efficacy of which in breast benign and malignant masses.Results The diagnostic efficacy results of elastography

elastography combined with stiff ring sign

and elastography histogram analysis for breast masses:the diagnostic efficacy of the histogram analysis [area under the curve was 0.93（0.85～0.96）] was superior to the elastic imaging combined with stiff ring sign[area under the curve was 0.87（0.82～0.93）] and elastography [area under the curve was 0.81（0.79～0.87）].Conclusion Ultrasound elastography histogram analysis method is helpful for the differential diagnosis of benign and malignant breast masses.The stiff ring sign can also improve the accuracy of elastography.
