Nouvelles modalités d’imagerie pour la radiothérapie : imagerie fonctionnelle et moléculaire

International audienceFunctional imaging with positron emission tomography (PET) is interesting to optimize radiotherapy planning, and probably to perform dose redistribution in many cancers. However, in 2015, fluorodeoxyglucose (FDG)-PET is validated only for therapy planning for lung cancer. The interest of dose painting, PET in non-lung cancers, the interest of other tracers (even PET hypoxia tracers), DW-MRI, and PET-MR for radiotherapy needs to be demonstrated in prospective multicentric phase III studies on large series of patients
