Figure 1.
US images of an 8 mm lesion in the left breast of a 41-year-old woman. (a) B-mode image shows a round, non-circumscribed, hypoechoic lesion. This was classified as BI-RADS 4b by two readers and 4c by the other two. (b) VTIQ elastography shows an SWVmax of 3.18 m/s. (c) Spectral Doppler demonstrates an RI of 0.63. (d) Kinetic analysis of the CEUS data calculates an mTTl of 29.06 s. All quantitative parameters were below the respective cut-off values, thus mpUS was considered negative. US-guided needle biopsy demonstrated a fibroadenoma.
