“…In addition, among the 74 benign breast masses (61.7%) classified as BI-RADS category 4a, 26 (35.1%) showed negative results on elastography and 48 (64.9%) were negative on US-CAD (Table 3). Based on our results, by applying elastography and US-CAD to breast US, we may be able to confidently improve the specificity of the diagnosis of breast masses, consistent with earlier studies showing that elastography was able to reduce the number of benign biopsies of category 4a lesions [14,20,21]. …”

PurposeThe aim of this study was to evaluate and compare the diagnostic performance of grayscale ultrasonography (US), US elastography, and US computer-aided diagnosis (US-CAD) in the differential diagnosis of breast masses.MethodsA total of 193 breast masses in 175 consecutive women (mean age, 46.4 years) from June to August 2015 were included. US and elastography images were obtained and recorded. A US-CAD system was applied to the grayscale sonograms, which were automatically analyzed and visualized in order to generate a final assessment. The final assessments of breast masses were based on the American College of Radiology Breast Imaging Reporting and Data System (BI-RADS) categories, while elasticity scores were assigned using a 5-point scoring system. The diagnostic performance of grayscale US, elastography, and US-CAD was calculated and compared. ResultsOf the 193 breast masses, 120 (62.2%) were benign and 73 (37.8%) were malignant. Breast masses had significantly higher rates of malignancy in BI-RADS categories 4c and 5, elastography patterns 4 and 5, and when the US-CAD assessment was possibly malignant (all P<0.001). Elastography had higher specificity (40.8%, P=0.042) than grayscale US. US-CAD showed the highest specificity (67.5%), positive predictive value (PPV) (61.4%), accuracy (74.1%), and area under the curve (AUC) (0.762, all P<0.05) among the three diagnostic tools. ConclusionUS-CAD had higher values for specificity, PPV, accuracy, and AUC than grayscale US or elastography. Computer-based analysis based on the morphologic features of US may be very useful in improving the diagnostic performance of breast US.

“…In this meta-analysis, good pooled sensitivities and specificities for SWI were shown based on maximum stiffness (93%, 81%, respectively) and on mean stiffness (94%, 71%, respectively) (Table 3, 74). Another SWI study of 83 breast lesions found a similar sensitivity and specificity of 94% and 73% respectively (Table 3, 75). …”

“…The R perilesion assesses the hardest portion of the peri-lesion area (E perilesion ) and the softest healthy fatty tissue (E fat ) through the ratio: R perilesion = E perilesion / E fat . They showed that using benign SWI signs (homogeneity and R perilesion < 4.32), to selectively downgrade B-mode US classified BI-RADS 4a (low suspicion for malignancy) and BI-RADS 4b (intermediate suspicion for malignancy) lesions improved specificity of US (13% to 51%) without loss in sensitivity (100%) (Table 3, 75). Berg et al performed a study with 958 women with breast lesions showing that SWI improved the specificity of B-mode US (61.1% to 78.5%) (Table 3, 76).…”

Elastography-based imaging techniques have received substantial attention in recent years for non-invasive assessment of tissue mechanical properties. These techniques take advantage of changed soft tissue elasticity in various pathologies to yield qualitative and quantitative information that can be used for diagnostic purposes. Measurements are acquired in specialized imaging modes that can detect tissue stiffness in response to an applied mechanical force (compression or shear wave). Ultrasound-based methods are of particular interest due to its many inherent advantages, such as wide availability including at the bedside and relatively low cost. Several ultrasound elastography techniques using different excitation methods have been developed. In general, these can be classified into strain imaging methods that use internal or external compression stimuli, and shear wave imaging that use ultrasound-generated traveling shear wave stimuli. While ultrasound elastography has shown promising results for non-invasive assessment of liver fibrosis, new applications in breast, thyroid, prostate, kidney and lymph node imaging are emerging.Here, we review the basic principles, foundation physics, and limitations of ultrasound elastography and summarize its current clinical use and ongoing developments in various clinical applications.

“…SWE has been used to evaluate liver stiffness and stiffness of breast (13,14), prostate (15,16), and thyroid lesions (17). SWE seems to increase specificity and positive predictive value in the assessment of breast (18,19) and prostate lesions (15).…”
