(A-F): Age distribution and imaging characteristics of each molecular subtype: (A) Mean age of TNBC was significantly less than the other subtypes. (B) Majority of tumors in each subtype were more than 20mm. (C) Circumscribed tumors were more likely to be TNBC type. (D) Posterior shadowing was commonly seen in LA and LB subtype, and posterior enhancement was seen in TNBC type. (E) Microcalcifications were most commonly present in HER2+ tumors. (F) LB and HER2 type were more vascular compared to others
