DCE-MR images of a patient who suffered from breast carcinoma and received the chemotherapy started with anthracyclines, DWI and ADC images in non-pCR group. Red color represent high ADC value, green color represent mediate ADC value, and blue color represent low ADC value. a, d DCE-MR images at baseline and postT2, There was an irregular mass in the right breast and confirmed to be breast carcinoma with Basal-like subtype. After two cycles of NAC, the tumor size didnʼt have no significant decrease in diameter. b, e DW images at baseline and postT2, The images showed how the whole volume of interest (VOI) was placed within the tumor area manually. c, f ADC maps at baseline and postT2, ADC values were 0.9345 × 10^− 3 mm²/s at baseline and 1.3320 × 10^− 3 mm²/s at postT2, ADC value varied significantly as early as postT2
