Summary

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.
