Aim/Introduction: An 18F-FDG-PET/CT examination requires the patient to follow instructions before and during the examination procedure to ensure a high image quality. There is thus a need to develop ways to ensure that patients absorb the information given in connection with the examination. Aim To develop communication support for information sharing related to an18F-FDG-PET/CT examination. Materials and Methods: The study has a qualitative design adapting a multiphase structure. A prototype of the communication support consisting of illustrations and text related to an 18F-FDG-PET/CT examination was developed. Interviews were conducted with patients scheduled for an 18F-FDG-PET/CT examination for the frst time and questionnaires were collected from health care professionalswith experience of 18F-FDG-PET/CT. The communication support was revised until consensus about the material. Results: The results are based on interviews with patients (n=10) and questionnaires collected from health care professionals (n=9).The overall theme revealed that information in conjunction with the 18F-FDG-PET/CT examination is a balancing act betweentext and illustrations. The analysis showed two categories;“illustrations as a complement” and “easy to understand lay-out”. Conclusion: The participants strengthened the development of the communication-support by bringing in valuable viewpoints from various perspectives. The results support a person-centered approach, where the information in conjunction with an 18F-FDGPET/CT examination can be adapted to each patient’s needs as a balancing act between text and illustrations.
