“…From a methodological point of view, agreement rate is an indicator for a new, experimental diagnostic method [11]. According to our results, ABVS and UE both displayed substantial inter-examiner agreement (ABVS: κ = 0.62, UE: κ = 0.65).…”

BackgroundAutomated breast volume scanner (ABVS) and US elastography (UE) have been useful for the differentiation of benign and malignant lesions. However, combining these two methods applied in diagnosis of breast lesions has not yet been reported. The aim of this study is to analyze the inter-examiner reliability of ABVS and UE, and compare diagnostic performance among ABVS, UE, and the combination of these two methods.MethodsForty-one patients (forty-six lesions) underwent both ABVS and UE examinations. ABVS images were acquired by medial and lateral scans for each breast and classified a BI-RADS category based on the distribution, size, shape, echogenicity and microcalcification of the lesions. UE images were assigned an elasticity score according to the distribution of strain induced by light compression. Kappa statistics was used to examine the reproducibility between examiners with ABVS and UE, and the concordance between pathology and ABVS, UE, and the combination of these two methods. χ2 test was used to compare diagnostic performance among these three methods.Two examiners blinded to the patients’ history evaluated the results of breast imaging independently.ResultsInter-examiner reliability with ABVS (κ = 0.62, 95% confidence interval (CI): 0.44-0.80) and UE (κ = 0.65, 95% CI: 0.48-0.82) was substantial. With respect to the pathology results, the inter-rater coefficient of concordance was κ = 0.81 (95% CI: 0.64-0.98) for ABVS, κ = 0.77 (95% CI: 0.58-0.96) for UE, and κ = 0.90 (95% CI: 0.77-1.00) for combination of ABVS and UE. Examiner variability was reduced from UE to ABVS, and to the combination of ABVS with UE.The diagnostic accuracy, sensitivity, and specificity for the combination of ABVS and UE were 95.7% (95%CI: 84.0-99.2), 100% (95% CI: 85.9-100), and 87.5% (95% CI: 60.4-97.8), respectively. When comparing, the diagnostic performance of ABVS combined with UE was better than, or at least equal to, that of ABVS (accuracy 91.3% (95% CI: 78.3-97.2), sensitivity 100% (95% CI: 85.0-1.00), specificity 77.8% (95% CI: 51.9-92.6)) or UE (accuracy 89.1% (95% CI: 75.6-95.9), sensitivity 96.4% (95% CI: 79.8-99.8), specificity 77.8% (95% CI: 51.9-92.6)) alone, though the improvement was no statistically significance.ConclusionsBoth ABVS and UE demonstrated substantial inter-examiner reliability. With high diagnostic performance for differentiation of benign and malignant lesions in the breast, the combination of ABVS and UE are useful to improve the diagnostic accuracy and specificity.

“…FDA has recommended approval for use in screening of women with dense breast parenchyma because it is unsusceptible to breast density [10]. However, with its striking practical advantages mentioned above, ABVS is accepted by other countries, and its diagnostic performance was not inferior to HHUS [11–17]. …”

“…The Acuson S2000TM ABVS is a highly advanced ultrasound system, which acquires the full-field volume of the breast, provides an efficient and comprehensive analysis of 3D data, and ensures accurate and consistent results for diagnosis. In addition, every section of the lesion can be easily displayed by the ABVS; more importantly, it is operator independent, providing more reproducible and reliable data [6,7]. Based on the advances of the ABVS, the detection rate of breast lesions has improved significantly, particularly for minor lesions.…”

“…For the detection of breast lesions, ABVS possesses certain advantages over US: 1) ABVS provides automated and standardized scanning; 2) reconstructed images can be saved and transmitted for later analysis, thereby facilitating remote consultation by allowing an assistant medical technician or radiographer to operate the device, a junior physician to analyze the images and report the findings, and a senior physician to interpret the findings and provide the final impression or diagnosis; 3) ABVS is less dependent on operator idiosyncrasies, so ABVS can reduce the impact of operator bias, thereby improving standardization and reproducibility (11,13,14); 4) overlooking a lesion is less probable with ABVS; compared to the small field of view provided by traditional 3D US (5 cm 2 ), ABVS offers a wider field of view covering the entire breast volume with one Japanese study demonstrating a whole breast visualization rate of up to 98% (15)(16)(17); and 5) unlike other imaging modalities, lesions that are not detected during breast US are not typically documented; however, ABVS has the potential to provide complete documentation (18).…”
