Audiovisual intervention alleviates anxiety of patients during PET/CT imaging

Aim to assess if the use of an audiovisual intervention in the uptake room and/or in the scanning room, could help to reduce anxiety during [18F]FDG PET/CT imaging. Methods We prospectively studied 120 patients referred for [18F]FDG PET/CT imaging. Patients were allocated in 4 groups of 30 patients depending on the use of the audiovisual intervention: (1) no audiovisual intervention; (2) audiovisual intervention only in the uptake room; (3) audiovisual intervention only in the scanning room; (4) audiovisual intervention in the uptake and the scanning rooms. In order to measure the anxiety levels of the patients before and after the scan, all patients answered the State-Trait Anxiety Inventory (STAI). Results The anxiety status across typical situations on a daily basis (STAI-T) of the 4 groups of patients was comparable with no significant differences. The mean State Anxiety (STAI-S) sum-score at prescan and postscan among groups was: (1) 17.5 +/- 8.7 vs. 17.3 +/- 8.6, p=0.834; (2) 17.4 +/- 10.5 vs. 15.8 +/- 9.6, p=0.110; (3) 17.5 +/- 11.7 vs. 15.1 +/- 9.8, p= 0.013; (4) 17.4 +/- 9.7 vs. 14.9 +/- 8.1, p= 0.009. The percentage of patients with reduction of the STAI-S score among groups 1-4 was 17%, 47%, 50%, and 66%, respectively. The variation of the percentage of patients with lower scores after intervention among groups was statistically significant (p<0.001). Conclusion Audiovisual intervention decreases anxiety levels of patients referred for PET/CT imaging. The results of our study support a beneficial effect of the audiovisual intervention and its potential to alleviate the anxiety of oncological patients who undergo a PET/CT scan.
