Receiver operating characteristic curves of B-mode US alone and combined use of shear-wave elastography (SWE) and color Doppler US.

<p>(a) For the total 67 fibroepithelial lesions, the area under the curves (AUCs) for ‘E_mean >43.9 kPa or high vascularity*’ (0.786, left) and ‘E_max > 46.1 kPa or high vascularity*’ (0.755, right), were compared to the AUC of B-mode US (0.687). (b) For the subgroup of 30 equivocal fibroepithelial lesions, AUCs for ‘E_mean >43.9 kPa or high vascularity*’ (0.719, left) and ‘E_max > 46.1 kPa or high vascularity*’ (0.656, right) were compared to the AUC of B-mode US (0.558). *Equal to or greater than 2 vessel-flow signals were observed on color Doppler US.</p

A 36-year-old woman diagnosed with equivocal fibroepithelial lesion by US-guided biopsy, which was confirmed as fibroadenoma on surgical excision.

<p>(a) The B-mode US image shows a 1.4-cm breast mass with BI-RADS category 4a (arrows), (b) the color Doppler US image shows low vascularity, and (c) the SWE image shows E_mean of 12.8 kPa and E_max of 17.1 kPa.</p

A 64-year-old asymptomatic female with an abnormality on screening mammography.

<p>(A) Magnification mammography demonstrates pleomorphic clustered microcalcifications in the right lower outer breast. (B) This lesion shows tubular isoechoic lesion with microcalcifications on US. The pathologic findings of both Wi-UVAB and surgical excision were pleomorphic LCIS.</p
