Nobody has “getting MRI scans” listed as their favorite free time activity which is totally understandable.
However for some of us undergoing such procedure is more than just inconvenience. Being trapped in a tube with no room to move around can be frustrating even for the bravest. If you suffer from claustrophobia (an irrational fear of being closed in a small space and having no escape) you often find yourself avoiding situations where you could panic again. This excludes you from a lot of different adventures and sometimes from potentially life-saving diagnostic examinations too.
