Dynamic changes of various MR parameters of cervical cancers during concurrent chemo-radiotherapy (CCRT). a D and apparent diffusion coefficient (ADC) values of cervical cancers increase during the course of CCRT and the D values are lower than the ADC values. b f values of cervical cancers increases initially and decreases after 4 weeks of therapy. c D* values of cervical cancers share the same tendency as f. d Tumor sizes shrink over the course of CCRT. Time point 1, before CCRT within one week; time point 2, at the end of the second week of CCRT; time point 3, at the end of the first month of CCRT; time point 4, immediately after CCRT within one week
