Diagnostic performance of the combined qualitative parameters of shear wave elastography (SWE) or/and AngioPLUS microvascular Doppler ultrasound technique (AP) with Breast Imaging Reporting and Data System (BI-RADS) in distinguishing malignant from benign lesions.
| Sensitivity (%) | Specificity (%) | Positive predictive value (%) | Negative predictive value (%) | Accuracy (%) | Area under the receiver operating characteristic curve (95%CI) | p a | |

| BI-RADS | 95.5 (64/67) | 46.9 | 45.7 | 95.7 | 62.4 | 71.2 (0.643–0.781) | – |
| BI-RADS + AP | 86.6 (58/67) | 79 | 65.9 | 92.6 | 81.4 | 82.8 (0.767–0.889) | <0.001 |
| BI-RADS + SWE | 91.0 (61/67) | 74.1 | 62.2 | 94.6 | 79.5 | 82.6 (0.767–0.885) | <0.001 |
