Abstract: Objective To compare the diagnostic value of sound velocity(SV) and real-time ultrasonic elastography in differentiating benign or malignant of breast lesions.Methods 75 patients with 99 lesions were examined with the zone speed index technique and real-time ultrasonic elastography respectively.Then the SVs of the lesions were calculated and elastography of the lesions were scored with 5-scoring method.The ROC curves were constructed with histology as the golden standard.Results There was significant difference between the SVs of benign and malignant breast lesions(P =0.0001).1561 m/s was the best cufoff point.And the areas under the curves (AUC) of SV and real-time ultrasonic elastography were 0.842 and 0.968,respectively.There was significant difference between the two methods of AUC (P =0.023).The sensitivity,specificity and accuracy for SV were 81.5％,91.7％,88.9％,respectively.There was no significant difference between sensitivity,specificity and accuracy of the two methods(P =1.0,P =0.125,P =0.146).Conclusions Both SV method and real-time ultrasonic elastography are helpful in the evaluation of benign or malignant of breast lesions.
