Necrotic index carcinoma with pathological non-complete response after neoadjuvant systemic therapy in a 30-year-old woman with TNBC of the left breast. The volume of necrotic material was 4 cm3, and the percent of the total tumor volume occupied by necrosis was 17%. a Axial fat-suppressed early-phase dynamic contrast-enhanced image shows central non-enhancing area representing necrosis (arrow). b Axial fat-suppressed T2-weighted image shows necrosis as a central area of high signal intensity (arrow). c Axial apparent diffusion coefficient map shows shine-through corresponding to central area of necrosis (arrow)
