The DIL volume, ADC value of the DIL, whole prostate volume, ADC value of the whole prostate, and PSA for both of the pre- and post-radiotherapy groups. The attributed number to the pre-treatment group was chosen 100. Then, the whole prostate volume, DIL volume, ADC value of the whole prostate, ADC value of the DIL, and PSA for the post-treatment groups were computed as percentages of it. Vertical bars represent standard deviation (SD) of the mean. *p < 0.05, **p < 0.01, ***p < 0.001
