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.
