Predictive model for contrast-enhanced ultrasound of the breast: Is it feasible in malignant risk assessment of breast imaging reporting and data system 4 lesions?

Figure 3 Receiver operating characteristic curve of logistic regression for contrast-enhanced ultrasound patterns. Nine independent variables were identified in the final step of the logistic regression analysis forward model: Enhancement intensity, enhancement time, enhancement direction, internal homogeneity, perfusion defect, crab claw-like pattern, nourishing vessels, margin and scope after enhancement. Area under the curve was 0.911.
