Radiomic feature maps between patients with different therapeutic responses before and after neoadjuvant chemotherapy. Heatmaps of the differential radiomic features between responsive patients and unresponsive patients a before neoadjuvant chemotherapy and b after neoadjuvant chemotherapy. Heatmaps of the differential radiomic features between before neoadjuvant chemotherapy and after neoadjuvant chemotherapy in c responsive patients and d unresponsive patients. Correlation matrix maps of the radiomic features generated from patients with response to the treatment e before neoadjuvant chemotherapy and f after neoadjuvant chemotherapy, and patients with no response to the treatment g before neoadjuvant chemotherapy and h after neoadjuvant chemotherapy. P values were calculated using the unadjusted log-rank test and paired samples t test
