“…3,11,12 Although different SWS-max cut-off values have been used due to the patient inclusion criteria, technical factors, pathological factors, or some unknown factors, the majority of previous studies showed that SWVmax achieves a high specificity (79.8-92.1%) and a moderate sensitivity (74.0-81.3%). [12][13][14] Our study revealed similar results. In this study, we acquired the maximum SWV of each lesion according to a standardized measurement method, and found a significantly higher SWVmax in malignant lesions (P < 0.0001).…”

Objective: To test the value of qualitative virtual touch imaging quantification (VTIQ) features in differentiating benign from malignant breast lesions. Methods: From November 2016 to August 2017, 230 lesions were subjected to conventional US and virtual touch imaging quantification before biopsy. The maximum shear wave velocity (SWVmax) was measured using a standardized method. Qualitative VTIQ features, including the "stiff rim" sign and color pattern classification, were assessed according to a binary classification. The sensitivity, specificity and area under the receiver operating curve (AUC) of Breast Imaging Reporting and Data System (BI-RADS), SWVmax, qualitative VTIQ features, and combined data were compared. Results: Among the 230 breast lesions, 150 were benign and 80 were malignant. Compared to the benign lesions, the malignant ones had higher SWVmax values and were more likely to show the "stiff rim" sign and VTIQ pattern 2 (P <0.001 for all). The AUC value was 0.885 for the qualitative VTIQ combination (the presence of the "stiff rim" sign and/or the display of VTIQ pattern 2), similar to that for SWVmax (P=0.472). BI-RADS combined with the qualitative VTIQ combination and with SWVmax yielded similar results, including significantly higher AUC values (P = 0.018 and 0.014, respectively), significantly higher specificities (P<0.001 for both), and nonsignificantly decreased sensitivities (P = 0.249 for both) compared to BI-RADS alone. Conclusion: The dual-category classification of qualitative VTIQ features according to the presence of the "stiff rim" sign and/or the classification of VTIQ pattern 2 is a simple and useful method that may be representative of quantitative VTIQ parameters in the evaluation of breast masses.

“…Therefore, the STE imaging is also called as “ultrasonic elastic imaging”. STE calculates the elastic modulus of the tissue at the detected shear wave propagation speed [ 18 ], in kPa, and color-codes the image at the same time to obtain color shear-wave images. In this study, benign masses with PAS mainly showed blue color on elasticity imaging, which was consistent with the color of surrounding tissues, and the Emean , Emax , and Esd values were small.…”

Background To assess the stiffness of benign breast masses in ultrasound images with posterior acoustic shadowing (PAS) and malignant lesions, and explore the significance of differential diagnosis using ultrasound real time shear wave elastography. Material and methods All 117 mammary masses (98 patients) with PAS were assessed by using routine ultrasound examination, and elastic modulus values were obtained with the real time shear wave elastography mode. All breast lesions were confirmed by surgery or biopsy. The significance of differences in ultrasound elastography values between breast benign and malignant masses with posterior acoustic shadowing was assessed, and the ROC curves of elasticity modulus values were analyzed. Results Among the 117 masses, 72 were benign and 45 were malignant. The two types of breast masses showed significant differences in size, margin, internal echo, calcification, and blood flow characteristics (P < 0.05), although the difference in orientation was not significant (P > 0.05). Emean, Emax and Esd obtained with real time shear wave elastography showed statistically significant differences between benign masses with posterior acoustic shadowing and breast cancer (P < 0.05), while Emin showed no significant difference between them (P = 0.633). Ultrasound real time shear wave elastography showed higher sensitivity and specificity than conventional ultrasound. Conclusions Benign and malignant breast masses with PAS show different ultrasound manifestations. Real time shear wave elastography can facilitate the differential diagnosis and treatment planning for these breast masses.

“…Erste Studien zur Ultraschall-Elastografie konzentrierten sich auf die Durchführbarkeit der verschiedenen Methoden und die Elastografie als eigenständige Untersuchung im Vergleich zum B-Mode-Ultraschall [8,[12][13][14]. Die meisten Studien fanden heraus, dass die Elastografie eine B-Mode Untersuchung nicht ersetzen konnte, obwohl die Spezifität tendenziell höher war als im B-Mode, wie auch ein aktueller Artikel in der EJU zeigt [15]. Später lag der primäre Fokus mehrerer Studien auf der Kombination von Elastografie und konventionellem B-Mode-Ultraschall und diese zeigten weitgehend überzeugende Resultate [11,16].…”

“…Early studies of ultrasound elastography focused on the feasibility of the different techniques and the comparison of elastography compared to B-mode ultrasound as a stand-alone examination [8,[12][13][14]. Most studies found, that elastography could not replace the B-mode examination, although specificity tended to be higher than for B-mode examinations as also demonstrated by a recent article in EJU [15]. Later, the combination of ultrasound elastography with the conventional B-mode examination was the primary focus of several studies, generally showing convincing results [11,16].…”
