“…The diagnostic performance of SWE is good for differentiating between benign and malignant breast lesions. In literature, the median sensitivity, specificity, and area under receiver operating curve of each quantitative parameter have been reported as follows: 88.6% (range, 81.0% to 95.8%), 89.9% (range, 68.2% to 93.8%), and 0.932 (range, 0.788 to 0.974) for E mean ; 90.3% (range, 60.9% to 97.0%), 81.8% (range, 77% to 100%), and 0.931 (range, 0.741 to 0.961) for E max ; 89.2% (range, 83.1% to 91.1%), 91.1% (range, 67.9% to 93.0%), and 0.899 (range, 0.761 to 0.964) for E SD ; and 88.0% (range, 71.4% to 96.7%), 93.7% (range, 90.6% to 100%), and 0.952 (range, 0.917 to 0.987) for E ratio , respectively [ 3 , 6 , 7 , 12 - 15 , 17 , 21 - 26 , 32 , 34 - 39 ]. The best-performing SWE parameter in diagnosing breast lesions has been reported to be E max or E ratio [ 15 , 19 , 25 , 26 , 38 , 40 ].…”

Shear-wave elastography in breast ultrasonography: the state of the art

Shear-wave elastography (SWE) is a recently developed ultrasound technique that can visualize and measure tissue elasticity. In breast ultrasonography, SWE has been shown to be useful for differentiating benign breast lesions from malignant breast lesions, and it has been suggested that SWE enhances the diagnostic performance of ultrasonography, potentially improving the specificity of conventional ultrasonography using the Breast Imaging Reporting and Data System criteria. More recently, not only has SWE been proven useful for the diagnosis of breast cancer, but has also been shown to provide valuable information that can be used as a preoperative predictor of the prognosis or response to chemotherapy.

“…The standard deviation represents the internal heterogeneity of the mass ( 5 6 ). Several studies have demonstrated the efficacy and diagnostic accuracy of SWE in the diagnosis of solid breast masses, and the combination of B-mode US with SWE was considered beneficial in the assessment of breast lesions using different quantitative parameters and cutoff values of SWE ( 2 3 4 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 ).…”

This study aimed to evaluate the diagnostic value of combining the quantitative parameters of shear wave elastography (SWE) and superb microvascular imaging (SMI) to breast ultrasound (US) to differentiate between benign and malignant breast masses. Materials and Methods: A total of 200 pathologically confirmed breast lesions in 192 patients were retrospectively reviewed using breast US with B-mode imaging, SWE, and SMI. Breast masses were assessed based on the breast imaging reporting and data system (BI-RADS) and quantitative parameters using the maximum elasticity (Emax) and ratio (Eratio) in SWE and the vascular index in SMI (SMIVI). The area under the receiver operating characteristic curve (AUC) value, sensitivity, specificity, accuracy, negative predictive value, and positive predictive value of B-mode alone versus the combination of B-mode US with SWE or SMI of both parameters in differentiating between benign and malignant breast masses was compared, respectively. Hypothetical performances of selective downgrading of BI-RADS category 4a (set 1) and both upgrading of category 3 and downgrading of category 4a (set 2) were calculated. Results: Emax with a cutoff value of 86.45 kPa had the highest AUC value compared to Eratio of 3.57 or SMIVI of 3.35%. In set 1, the combination of B-mode with Emax or SMIVI had a significantly higher AUC value (0.829 and 0.778, respectively) than B-mode alone (0.719) (p < 0.001 and p = 0.047, respectively). B-mode US with the addition of Emax, Eratio, and SMIVI had the best diagnostic performance of AUC value (0.849). The accuracy and specificity increased significantly from 68.0% to 84.0% (p < 0.001) and from 46.1% to 79.1% (p < 0.001), respectively, and the sensitivity decreased from 97.6% to 90.6% without statistical loss (p = 0.199). Conclusion: Combining all quantitative values of SWE and SMI with B-mode US improved the diagnostic performance in differentiating between benign and malignant breast lesions.

“…Ultrasound (US) imaging is an important examination method that vividly reflects the characteristics of breast cancer masses, such as tumor size, tumor shape, growth orientation, margin, posterior features, calcifications, and echogenicity, according to the US lexicon of fifth edition of the American College of Radiology Breast Imaging Reporting and Data System (BI‐RADS) . Numerous studies have demonstrated that the use of US features can distinguish malignant breast lesions from benign ones . Some researchers revealed significant correlations of US features with molecular markers such as estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) and even molecular luminal A, luminal B, and basal‐like subtypes .…”
