Cardiac coherence, a breathing technique aimed at synchronizing heart rate and reducing anxiety, has shown benefits in stress management. This randomized controlled trial aims to evaluate whether the use of a guided cardiac coherence exercise during MRI can improve exam success rates and image quality in self-reported claustrophobic patients compared to standard care (cartoons for children, music for adults). The primary outcome is the proportion of interpretable MRI scans with good-quality images, assessed blindly by a radiologist. Secondary outcomes include exam duration, use of the emergency call button, patient satisfaction, and perceived comfort. A total of 220 patients aged 7 years and older will be enrolled over 12 months at the Fondation Adolphe de Rothschild Hospital.",[44,45],"Claustrophobia","MRI","NOT_YET_RECRUITING","2025-12-29",{"date":49,"type":50},"2025-12-30","ACTUAL",{"date":52,"type":37},"2026-01",{"date":54,"type":37},"2027-12",{"name":5,"class":6}]
