This assertion stems from the high Claustrophobic Questionnaire results of those who reported anxiety during the scan. Almost 25% of the patients reported at least moderate feelings of anxiety during the scan and 3 were unable to complete the scan at all. When asked a month after their scan, 30% of patients (these numbers are taken of the 48 that responded a month later) reported that their claustrophobic feelings had elevated since the scan. The majority of these patients claimed to have never had claustrophobic sensations up to that point. This study concludes that the Claustrophobic Questionnaire (or an equivalent method of diagnosis) should be used before allowing someone to have an MRI.
