The present project aims to explore the effect of a hypnosis session performed on a patient with anxiety during a cardiac MRI examination on image quality.

Cardiac Magnetic Resonance Imaging (MRI) is an activity of the Bordeaux University Hospital that continues to grow (+7.3% in 2021 compared to 2019) under the combined effect of the increase in activity of cardiology care channels and the extension of clinical indications for cardiac MRI. Indeed, cardiac MRI has become an essential examination in the diagnosis of many heart diseases and is little practiced elsewhere in New Aquitaine. The current delay for a cardiac MRI is 3 and a half months.

In this context, it is necessary to be efficient because any procedure failure, examination interruption or insufficient image quality can delay the diagnosis and therapeutic management of the patient for several months. Numerous studies have shown that anxiety induces interruptions in the acquisition of MRI images and repetition of sequences, thus prolonging the examination time.

However, no study takes into account the specificity of cardiac MRI, whose image quality is intimately linked to the patient's cooperation and to the synchronization of the sequences with the heart rhythm.

Hypnosis seems to be adapted to reduce the patient's anxiety, by allowing him to ignore the surrounding reality while remaining in relation with the attendant.

The hypothesis is that by reducing patient anxiety through hypnosis, image quality in cardiac MRI would be improved.
