Fig. 2: A 44 year-old woman with TNBC undergoing NAST.

MRI at baseline (A), after two cycles (B), and four cycles (C) of AC shows an oval, heterogeneously enhancing mass with associated clip marker (arrows). MRI shows concentric shrinkage and tumor volume reduction of 83% after two cycles, and 96% after four cycles. Pathology after the completion of NAST confirmed pathologic complete response.
