Claustrophobia and Magnetic Resonance Imaging (CLAUSTRO)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00715806
Recruitment Status : Completed

Brief Summary:
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.

Primary Outcome Measures :
  1. The ability of an open MRI scanner to reduce claustrophobic reactions that prevent MR examinations. [ Time Frame: Before or During MRI ]

Secondary Outcome Measures :
