“…Because of the similar usefulness of BI-RADS-US descriptors in diagnosing breast lesions, it is significant to know how retraction phenomenon performed compared with BI-RADS-US descriptors in the differential diagnoses of breast lesions. Although the literature concerning the clinical application of ABVS has been currently increasing, studies have mainly focused on thediagnostic value of ABVS [11,12,13], its reproducibility [14,15,16], itscomparison with conventional US or mammography [8,9,10,17], disease size measurement [18,19], and its application to other organs or tissues [20,21]. To our knowledge, no investigators have compared the diagnostic performance of retraction phenomenon with BI-RADS-US descriptors using an ABVS.…”
