Synopsis

Keywords: Normal development, New DevicesMRI examinations in young children are typically performed during natural or induced sleep to reduce distress and movement artefacts. However, those approaches have high failure rate and/or carry risks. We describe a system for MR imaging in awake children which combines immersive and interactive MR compatible virtual reality, eye tracking, and robust post-acquisition motion correction. We demonstrate effectiveness in a pilot study with a 2 year old child who used the system on 3 occasions for average 19.5 minutes. The described approach opens new possibilities for awake MR studies in young children for both clinical and research purposes.
