Multiparametric ultrasound of a palpable, 17-mm large lesion in the craniolateral left breast of a 70-year-old patient. a In B-mode, the lesion was isoechoic, slightly heterogeneous, with a partially indistinct margin and an anti-parallel orientation and was classified as BI-RADS 4c. b In VTIQ elastography, the lesion demonstrated hard parts, with a SWVmax of 4.25 m/s. c Power Doppler showed abundant internal vascularity and the spectrum analysis of the most prominent artery demonstrated an RI of 0.82. The application of the classification algorithm would classify this lesion as node 2, with a very high probability of malignancy. Ultrasound guided biopsy revealed a Grade 1 mucinous carcinoma
