    It is now well demonstrated that (F)-fluorodeoxyglucose PET/CT is the most accurate imaging method for determining disease extent in Hodgkin lymphoma. Thus, up-front PET/CT is mandatory for involved node radiation therapy design. For a proper use of this new imaging modality for radiotherapy, some adaptations should be made to the PET/CT acquisition as well as to the report. Initial PET/CT should be performed in the radiotherapy treatment position. Nuclear medicine physicians should report to the radiation oncologist the precise location of each involved lymph node, for which the use of a common atlas of upper diaphragmatic nodal stations could be useful. All these new procedures have to be implemented in close collaboration among the different medical specialists providing care to Hodgkin lymphoma patients. We report here the usual procedures of PET/CT acquisition in the radiotherapy environment and propose a more sophisticated description of the different lymph nodes for a more efficient nuclear medicine report to the radiation oncologist.[Imagerie multimodale incluant la TEP/TDM au (18F)-fluorodĂ©soxyglucose pour ladĂ©linĂ©ation des champs d’irradiation du lymphome de Hodgkin localisĂ©] Il est maintenant clairement Ă©tabli que la TEP/tomodensitomĂ©trie au (18F)-fluorodĂ©soxyglucose est la technique d’imagerie de rĂ©fĂ©rence pour le bilan d’extension des lymphomes de Hodgkin. Par consĂ©quent, l’utilisation de la TEP/tomodensitomĂ©trie est indispensable pour la rĂ©alisation d’une radiothĂ©rapie de type involved-node. L’utilisation de cette imagerie fonctionnelle par les radiothĂ©rapeutes nĂ©cessite une acquisition des images et un compte rendu d’examen particuliers. La TEP prĂ©thĂ©rapeutique doit ĂȘtre rĂ©alisĂ©e en position de traitement. Le compte rendu doit dĂ©crire prĂ©cisĂ©ment l’ensemble des ganglions supposĂ©s envahis, raison pour laquelle une classification unique dĂ©crivant l’ensemble des aires ganglionnaires sus-diaphragmatiques est proposĂ©e. Cette nouvelle technique thĂ©rapeutique nĂ©cessite une collaboration Ă©troite entre diffĂ©rentes spĂ©cialitĂ©s mĂ©dicales. Cet article a pour objet la description de la rĂ©alisation pratique de la TEP/tomodensitomĂ©trie en position de radiothĂ©rapie ainsi qu’une trame de compte rendu d’examen prenant en compte la description des diffĂ©rents ganglions sus-diaphragmatiques
