Initial results of a prostate cancer study investigating whether multiparametric MRI (MP-MRI), involving diffusion-weighted (DW) and dynamic contrast-enhanced (DCE) MRI, can predict or assess tumour response to radiotherapy (RT) and potentially support adaptive radiotherapy for high-risk patients. Adaptive radiotherapy is a treatment technique utilised to minimise radiation related toxicity. For some cancers it is possible to adapt radiotherapy according to physical changes that occur during treatment. This is not appropriate for prostate cancer treatment since observable changes are generally due to rectal movement, however it may be possible to use multiparametric MRI (MP-MRI) to measure treatment response.
