Figure 5.
Functional tumor volume (FTV) plots and their mean (red circle) corresponding to optimal percentage enhancement (PE) and signal enhancement ratio (SER) for patients with pathologic complete response (pCR) and non-pCR. Plots correspond to images obtained (a,b) at baseline (BL), 1 min (a), and 2.5 min (b) after contrast agent injection; (c,d) after the second cycle of neoadjuvant systemic therapy (NAST) (C2), at 1 min (c), and 2.5 min (d) after contrast agent injection; and (e,f) after the fourth cycle of NAST (C4), at 1 min (e), and 2.5 min (f) after contrast agent injection.
