Contrast-enhanced Spectral Mammography (CESM) Early Quantitative Evaluation of Tumoral Response and Pathologic Complete Response Prediction for Localized Breast Cancer Treated by Neoadjuvant Chemotherapy

"* Inclusion visit (V1) Initial baseline CESM (V2) 15 days after inclusion~* First chemotherapy treatment (V3) 28 days after V2.~* Unilateral follow-up CESM (V4) 4 to 6 weeks after the first course of chemotherapy.~* Surgery (V5):~ 3 to 6 weeks later at the end of the complete treatment with primary chemotherapy~* End of research visit (V6) It corresponds to the histological analysis on the surgical specimen after the complete treatment with neoadjuvant or primary chemotherapy."
