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 1 Predictive models for contrast-enhanced ultrasound of malignant breast lesions. A: Hyper-enhancement, enlarged size after enhancement, irregular shape, IDC; B: Hyper-enhancement, centripetal enhancement, enlarged size, present perfusion defect (red arrow), IDC; C: Rapid wash-in with hyper-enhancement, present penetrating vessels (black arrow), IDC; D: Rapid wash-in with hyper-enhancement, present crab claw-like pattern (white arrows); IDC; E: Synchronous wash-in with iso-enhancement, with perfusion defect (red arrow), DCIS. IDC: Invasive ductal carcinoma; DCIS: Ductal carcinoma in suit.
