Change in ADC Values in the Prostate During Radiotherapy.

Daniel Wilson¹, Sarah Bacon¹, Alastair McCabe¹, Brendan Carey²

The apparent diffusion coefficient (ADC) was measured in the prostate pre- and post-external beam radiotherapy in 17 patients`. There was a significant reduction in ADC post radiotherapy in both normal and malignant regions. Further measurements of ADC at other time points are needed to fully characterise the time course of any changes.
