    Scanning children is a challenge for clinical and research purposes since movement artifact affects severely the quality of the exam. Although clinical protocols have been optimized to reduce movement on acquiring a high quality pediatric brain scan without sedation, the success is limited. Moreover, for research purposes, alternative methods to sedation have been proposed with positive outcome but with intensive training and time consuming. Aims: In this study, we evaluated the use of a thirty-minute playful technique for preparing children and adolescents for a brain MRI research protocol. Methods: A total of 781 subjects (430M/351F) from 6-14 years-old were invited to perform a brain MRI protocol in two centers. In one center the intervention was individual and in the other was in group. Prior to the scan, subjects underwent a playful technique which included dance, relaxation, music, and recreational and interactive games. Results: Overall, 96% of the children (749/781) submitted to the playful intervention performed an MRI scan. All scans had diagnostic quality. Older children had a higher change of performing a scan without movement (OR= 1.16, p= 0.004), and overtime the chance of delivering a MRI sequence without movement decreases (OR= 0,43; p<0,001). The success rate of acquiring a scan without movement varied from 98,5-70 % overtime. Children who received individual intervention had 3.53 chances (p<0.001) of a successful imaging (i.e., without movement) compared to those who were exposed to group intervention. No gender effect was observed on images quality (OR=- 0,72; p=0,081). Conclusion: Our results suggest that our therapeutic protocol is effective in preparing children and adolescents for a research MRI scan and should be considered as a potential alternative technique to be used in medical diagnostic imaging centers.
