Illustration of the DSC calculation. First, tumour ROIs for a rectal motion-free slice (b = 1000 s/mm2) were delineated using the two-step drawing approach. DSC values were then calculated for DPsti-TSE ROI and DW-EPI ROI separately. The DSC value is the ratio of the overlapped area to the mean area of two ROIs, from a DW image and the T2-weighted image, respectively. (DPsti-TSE diffusion-prepared stimulated echo turbo spin-echo, DSC Dice similarity coefficient, DW-EPI diffusion-weighted echo-planar imaging, ROI region of interest)
