Abstract: Objective To explore the application of contrast-enhanced scoring system in the diagnosis of breast tumor.Methods 249 patients with 260 lesions were examined by elastography and contrastenhanced ultrasound before surgery.All the lesions were scored according to the two different methods.Pathological results were made the golden criteria.The diagnosis accuracy of the two methods were compared.Results There were 145 benign and 115 malignant tumors.The diagnosis accuracy,specificity and sensibility of elastography were 85.0％,88.3％,80.1 ％ respectively.The critical value of contrastenhanced ultrasound was between 3 and 4.The diagnosis accuracy,specificity and sensibility of contrastenhanced ultrasound were 88.9％,87.6％,90.4％ respectively.Area under ROC curve of the two methods were 0.901 and 0.910,the difference was not statistically significant.Conclusions Contrast-enhanced ultrasound 5-point scoring system was an initial quantitative criterion for breast tumor diagnosis.The diagnosis accuracy was parallel to that of elastography.
