Influence of Music in Anxiety Reduction in 18F-FDG PET-CT Studies

Abstract

Purpose:The purpose of this investigation was to find the anxiety levels, physical data and subjective perception and explore the relationship between demographic, clinical and cancer patients' variables, pre and post-procedure during a positron emission tomography/computed tomography PET-CT scan. Methods:The sample was distributed in two groups (experimental and control group), 54 subjects in each group, with clinical indication for performing an 18F-2fluoro-2-deoxy-D-glucose [18F]FDG-PET/CT scan. The study was conducted using an ad hoc questionnaire and the standardized State-Trait Anxiety Inventory (STAI) The pre-procedure questionnaire focused on demographic information, oncological situation, subjective perception of anxiety and STAI test. The post-procedure questionnaire included the subjective perception anxiety and STAI test after the procedure. Prior to the PET-CT, most of participants do not exhibited physical symptoms.Results: Regarding the effectiveness of the intervention, we found a significant effect on the level of post-intervention subjective anxiety, controlling for the effect of pre-intervention anxiety levels (F = 496.599; p = 0.000; η 2 partial = 0.82). Statistically significant differences were found between the control group and the music group. With respect to the effectiveness of the music on the post-intervention STAI state anxiety score we found significant differences between the intervention group and controls (F = 416.408; p = 0.000; η 2 partial = 0.79). The music group (11.72) presented lower corrected mean scores on the post-intervention STAI state anxiety scale, showing statistically significant differences with the control group. Conclusions:In conclusion, our work shows that relaxing meditative music can be used as a relaxation and anxiolytic mechanism as an integral multimodal part in patients during the uptake phase before PET-CT studies.
