Magnetic resonance imaging is an important and increasingly prevalent imaging modality used in healthcare. Children often find the procedure anxiety provoking causing difficulty in staying still and providing quality images. The use of preparation techniques including play therapy and role play utilizing such tools as a fiberglass mock MRI have shown to reduce anxiety and facilitate better image quality. Modalities of preparation including Virtual Reality (VR) pose as an alternative to habituate children for a MRI procedure.

On this virtual reality headset, it will be loaded with an educational virtual reality mock MRI training titled "Ready Teddy". This training explains the procedure to the viewer and addresses common questions that individuals often have regarding an MRI. Furthermore, using audio/visual cues, when the viewer moves their head too much in a MRI like setting they are reminded to stay still. Biofeedback training is aimed to mimic the experience of the MRI with real audio recordings of image acquisition, in order to adequately train the view to stay still in an MRI procedure.

Childhood Anxiety Sensitivity Index (CASI)
This 18-item measure utilizes a three-point Likert scale (none (1), some (2), a lot (3)) to assess how negatively patients view anxiety symptoms. Items are summed with a higher score indicating greater anxiety sensitivity.
Time frame: Approximately 5 minutes to one hour before procedure
Number of Participants with Successful Imaging without Sedation
A successful image will be produced after MRI. Failure would mean the child is rescheduled for another MRI with sedation.
Time frame: Up to thirty minutes after intervention
Visual Analogue Scale (VAS)
The VAS anticipatory anxiety measure is a vertical VAS, anchored with 0 at the bottom indicating the least amount and 10 at the top indicating the greatest amount, in response to the instruction to rate "how nervous, afraid, or worried" they were about the upcoming task. The scale also has color cues, graded from yellow at the bottom to dark red at the top, as well as a neutral face at the bottom and a face showing a negative expression at the top. Prior research used the VAS to rate anticipatory anxiety and pain in children
Time frame: Approximately 5 minutes to one hour before intervention
Faces Pain Scale-Revised (FPS-R)
Revised is an updated version of the Wong-Baker Faces Pain Rating Scale depicting no pain as a neutral expression as compared with the smiling face of the original measure. The child is asked to point to the face cartoon that depicts how they are currently feeling because of their pain. Face measures are thought to measure pain intensity, and the Wong-Baker Faces measure has demonstrated good reliability and validity.
Time frame: Approximately 5 minutes to one hour before procedure
Child Anxiety Meter State (CAM-S)
The child is asked to color a thermometer that has ten marks to indicate their level of anxiety they feel at the moment. The meter can be translated to a 0-10 scale with higher score indicating greater anxiety.

Time frame: Approximately 5 minutes to one hour before procedure
Child Anxiety Meter Trait (CAM-T)
The child is asked to color a thermometer that has ten marks to indicate their level of anxiety they usually feel at home. The meter can be translated to a 0-10 scale with higher score indicating greater anxiety.
Time frame: Approximately 5 minutes to one hour before procedure
Demographics
24 Item questionnaire which asks parents demographic questions regarding socioeconomic data.
Time frame: Up to one hour before intervention
