Fig. 2From: Comparison and risk factors analysis of multiple breast cancer screening methods in the evaluation of breast non-mass-like lesionsHand-held ultrasonography and automated breast ultrasonography non-mass-like lesion findings with asymmetry (MG). A Large irregular block shadow with fuzzy and rough boundary and a large number of burrs like shadows of different lengths could be seen in the upper right breast area of MG, ACR BI-RADS 4A. B HHUS showed a patchy heterogeneous echo area in the right breast with irregular thickened duct structure. The thickened duct was hypoechoic. CDFI showed a little color blood flow signal in this area, Adler Grade 2, IA grade (K.O), ACR BI-RADS 4B. C The coronal plane of ABUS in the right breast showed patchy and uneven echo area with irregular shape, fuzzy edge and uneven internal echo. ACR BI-RADS 4B.
