The objective of the present project is to validate the feasibility of a multimodal radiological pathway while on chemoradiotherapy, in order to validate potentially predictive factors for chemoradiotherapy sensitivity of rectal adenocarcinomas.~It is based on a structured clinical and radiological pathway for patients, using diffusion MRI and F misonidazole PET.~Validation of these new tools is already needed in clinical practice since future institutional trials will be based on treatment individualisation, using preoperative predicting factors.
