Methods: A total of 166 breast tumor patients who underwent conventional ultrasound and 2D and 3D RTE examinations were retrospectively analyzed. The 3D RTE images were divided into three types according to the occupancy of blue contrast images. Elastic scores (ES) were obtained by 2D RTE examination. The diagnostic accuracy of 3D and 2D RTE images in differentiating malignant from benign breast tumors was evaluated. Results: Of all cases, 89.4% of the malignant cases were Type 3 and 86.6% of the benign cases were Type 1 or 2 according to 3D RTE images.3D RTE Type 3 and ES≥4 on 2D RTE examination diagnosed malignant tumors with an accuracy of 87.4 and 88.6%, respectively. In addition, among 34 patients with an ES of 3, the presence of 3D RTE Type 3 diagnosed malignant tumors with an accuracy of 82.4%. Conclusion: In this study, the utility of 3D RTE images was comparable to that of ES on 2D RTE examination in differentiating malignant from benign breast tumors. In addition, utilizing 3D RTE images in cases with an ES of 3 on 2D RTE may increase the diagnostic accuracy for breast tumors.
