Résumé : Objectif: There are no guidelines regarding the content of information to be delivered in nuclear medicine. This study aimed at describing practices of French nuclear medicine physicians concerning results communication to patients undergoing PETs for oncological indications. Methodes: A survey was performed among French nuclear medicine physicians using an electronic questionnaire. Resultats: The study included 250 nuclear medicine physicians. Their practices regarding communication of PET results to patients were heterogeneous: (1) pre- and/or post-PET consultations were systematic for 56%, adapted on a case-to-case basis for 35%, and never performed for 9% of respondents; (2) oral communication of results was systematic for 13%, adapted on a case-to-case basis for 63%, and never performed for 24% of respondents. Working in a private center, presence of post-PET consultations, being older and more years of experience were significantly associated with more oral communication of results. Finally, 80% of physicians admit that current recommendations are not clear enough. Conclusion: The heterogeneity of practices among French nuclear medicine physicians concerning communication of PET results to patients probably results from lack of clear recommendations. An inter-collegial, ethical, and multi-disciplinary reflection is needed to better guide nuclear medicine physicians in relation to the communication of results to patients suffering from serious disease.
