Methods A total of 120 breast nodule patients (139 breast nodules) admitted to the Department of Nail and Breast Surgery, Subei People's Hospital from February to December 2018 were selected. All patients underwent ultrasound elastography scans. Strain elastography scans and measurements were performed first. Strain rate ratio (SR), then perform shear wave elastography inspection and measure the maximum elastic modulus (Emax). The ROC curve of two parameters for the diagnosis of benign and malignant breast nodules was drawn, and the area under the curve (AUC) and the corresponding cut-off value, accuracy, sensitivity, specificity, positive predictive value, and negative predictive value were calculated. Kappa consistency test was used to evaluate the diagnosti
