Fig. 3From: Amide chemical exchange saturation transfer at 7 T: a possible biomarker for detecting early response to neoadjuvant chemotherapy in breast cancer patientsMean APT signal and standard deviation within the ROI (tumor) for all ten lesions. a The mean APT signal after the first cycle of NAC is plotted versus the mean APT signal before the start of NAC for the nonresponders (red), partial responders (blue), and complete responders (green). b The mean change in APT signal is plotted versus the mean APT signal before NAC. The dashed lines in both a and b indicate the absence of a change in APT signal before and after the first cycle of NAC treatmentBack to article page
