Prostate ADC values were calculated using a variety of b-value combinations from b=0, 50, 300 and 500 s/mm2. The calculated ADC depended on the combination of b-values used. All combinations showed a decrease in ADC post radiotherapy compared to pre radiotherapy. This difference was statistically significant for all combinations except b=300 and 500 s/mm2 combined. This decrease in ADC may be a result of radiation induced cellular changes.
