  Purpose
The objective of the study is to determine the ability of open magnetic resonance imaging (MRI) scanners to reduce claustrophobic reactions, thereby enabling more examinations of severely anxious patients. The investigators hypothesize that anxiety-based claustrophobia that prevents MR examinations without sedation can be reduced using an open MR scanner design thereby improving clinical management of those patients.

Condition Intervention
Claustrophobia Device: Open MRI scanner. Device: Closed MRI scanner.

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Outcomes Assessor)
