Figure 3. An example of a responder (histological evaluation: Grade 1B). A, A right breast cancer showed an irregular margin before NAC on T1 weighted enhancement imaging; B, The DWI images superimposed on a T2 map for the selection of the ROI (circle); C, The T2 color map shows the lesion T2 relaxation time of 78.78 ms; D, The T2 relaxation time curve; E, The lesion decreased slightly in size after NAC on T1 weighted Gd-enhanced image; F, The DWI images superimposed on a T2 map for the selection of the ROI (circle) after NAC; G, H, After NAC, the lesion T2 relaxation time was 56.98 ms shorter than that before NAC.
