Clinical Trial Summary

This study evaluates if our Virtual Reality (VR) simulation inside the MRI efficiently alleviates symptoms of claustrophobia for patients during the MRI examination.

Description:

Anxiety of claustrophobic patients during MRI scan leads to movements of patients (which cause imaging artefacts), interruptions or even abortions of imaging scans, eventually requiring to reschedule the examination. Improving these symptoms by creating a VR experiences adapted to the physical constraints of the MRI environment, such as "disappearing the scanner", not only improves the subjective experience of the participant, but has immediate impacts the time spent on the examination, on personnel costs, and resource availability (scanner time).

This study aims at comparing claustrophobic patients in an A|B group design with or without VR intervention. Primary outcomes include subjective reports from patients (Acceptability and Demand) and practitioners (Implementation, Practicality, Adaptation, Integration, Expansion). Secondary outcomes include scanning efficacy based e.g. on the imaging quality, number of times a scan is interrupted by the user and the total duration of a scan. Another non-claustrophobic patients' group will be tested for for obtaining feedback on the general benefit of VR immersion on patients' experience.

• Claustrophobia
• Phobic Disorders

Intervention

Device:
• Immersion in virtual reality using Nordic Neurolab(™) Visual System
In addition to the standard MRI procedure, the VR intervention group will be looking at stereoscopic computer generated images through a pair of head-coil-mounted googles (Nordic Neurolab ™ Visual System). Two markers (color balls) will be fixed on their knees to capture their movement (camera tracking from the outside of the MRI room). The VR scenario will consist in showing a replication of the actual MRI examination room, as seen from the point of view of the participant lying on the MRI bed, but without the MRI tunnel. Participant can see themselves in the large room (a simplified gender-matched avatar), and an entertaining video can be displayed.
