“…According to the performance, the proposed strain feature set can be the complement to the conventional B-mode features for breast tumor diagnosis. The result is in agreement with Alhabshi et al [46] that the combining of strain and B-mode features obtained the best results in detecting carcinoma and in reducing unnecessary biopsy (Az ¼0.93 vs. Az ¼0.95 in [46]). …”

“…In a study using B-mode, strain pattern (elasticity score), width ratio, and strain ratio, Alhabshi et al (Alhabshi, Rahmat et al 2013) reported that width ratio and strain ratio were the most useful methods of lesion characterization, with a cut-off value of 1.1 for width ratio and a cut-off value of 5.6 for strain ratio. Stachs et al (Stachs, Hartmann et al 2013) demonstrated the FLR utility in 224 breast masses in 215 patients that the strain ratio was predominantly higher in malignant tumors, i.e., 3.04 6 0.9 (Mean 6 SD) for malignant tumors versus 1.91 6 0.75 for benign tumors.…”

The breast section of these Guidelines and Recommendations for Elastography produced under the auspices of the World Federation of Ultrasound in Medicine and Biology (WFUMB) assesses the clinically used applications of all forms of elastography used in breast imaging. The literature on various breast elastography techniques is reviewed, and recommendations are made on evidence-based results. Practical advice is given on how to perform and interpret breast elastography for optimal results, with emphasis placed on avoiding pitfalls. Artifacts are reviewed, and the clinical utility of some artifacts is discussed. Both strain and shear wave techniques have been shown to be highly accurate in characterizing breast lesions as benign or malignant. The relationship between the various techniques is discussed, and recommended interpretation based on a BI-RADS-like malignancy probability scale is provided. This document is intended to be used as a reference and to guide clinical users in a practical way.

“…There are also some authors that recommend higher cut-off values, up to 5.6 [40]. Also, some authors identified a specific threshold for malignant lesions, 3.04±0.9 with suggestive values for benign lesions, 1.91±0.75 [41].…”

Aims: To assess the quality of real time elastography as a differential diagnosis tool for breast nodules and to compare it with standard ultrasonography. Material and methods: In this prospective study we enrolled 174 patients in which 174 dominant breast nodules were considered for the final diagnosis. The results of ultrasonography and real time elastography, both qualitative and quantitative, were compared with pathology findings from the biopsy specimens. Results: Pathology examinations determined 102 nodules were benign and 72 malignant. Qualitative elastography had a better diagnostic performance (82.4% sensitivity and 81.9% specificity) than ultrasonography plus Doppler evaluation (70.3% sensitivity and 73.5% specificity). Quantitative elastography, assessed using the fat-to-lesion ratio, was a good discriminant for malignancy (AUROC = 0.93, p < 0.001). Our results pointed to an optimal threshold for malignancy of > 4.88; by using this threshold, the diagnostic reliability of the fat-to-lesion ratio was better than both ultrasonography and qualitative elastography (86.5% sensitivity and 90.4% specificity). Conclusion: Real time elastography is superior to ultrasonography in diagnosing malignant breast nodules. The evaluation of nodules using a fat-to-lesion ratio was a better discriminant for malignancy than qualitative elastography.
