Claustrophobia, an intense fear of confined spaces, can significantly impair the success of MRI examinations by causing patient movement or early termination of the scan, leading to poor image quality. 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.
