The mean value of DDC in non-responders group. a Axial T2WI, there was an irregular mass in cervix. b DWI (b = 800 s/mm2), the image showed the location of ROI during the tumor area. c ADC map, the final ADC value was high (=0.993 × 10− 3 mm2/s). d D map, the final D value was high (=0.876 × 10− 3 mm2/s). e DDC map, the final DDC value was high (=1.237 × 10− 3 mm2/s), which was higher than the cut-off value of DDC (=1.141 × 10− 3 mm2/s). f α map, the final α value was low (=0.621). g Twelve months after radiochemotherapy, the lesion decreased slightly. But the tumor size didnʼt achieve a sufficient shrinkage to qualify for partial response, therefore, the patient was classified as non-responders group
