Figure 2 : All images are contrast-enhanced, T1-weighted MR images. Top row shows baseline MR examinations, whereas the bottom row shows MR examinations after completion of neoadjuvant chemotherapy. Left column shows an example of complete response, in which the tumour disappeared completely and only the marker clip artifact (arrow) is still visible (Miller and Payne grade 5); middle column shows partial response, with some enhancing residual disease left (Miller and Payne grade 3); right column shows poor response (Miller and Payne grade 2).
