mri procedure

because can produce fear of both suffocation , restriction, mri scans prove difficult claustrophobic patients. in fact, estimates anywhere 4–20% of patients refuse go through scan precisely reason. 1 study estimates percentage high 37% of mri recipients. average mri takes around 50 minutes; more enough time evoke extreme fear , anxiety in severely claustrophobic patient.

this study conducted 3 goals: 1. discover extent of anxiety during mri. 2. find predictors anxiety during mri. 3. observe psychological factors of undergoing mri. eighty patients randomly chosen study , subjected several diagnostic tests rate level of claustrophobic fear; none of these patients had been diagnosed claustrophobia. subjected several of same tests after mri see if anxiety levels had elevated. experiment concludes primary component of anxiety experienced patients closely connected claustrophobia.

this assertion stems high claustrophobic questionnaire results of reported anxiety during scan. 25% of patients reported @ least moderate feelings of anxiety during scan , 3 unable complete scan @ all. when asked month after scan, 30% of patients (these numbers taken of 48 responded month later) reported claustrophobic feelings had elevated since scan. majority of these patients claimed have never had claustrophobic sensations point. study concludes claustrophobic questionnaire (or equivalent method of diagnosis) should used before allowing have mri.

use of virtual reality distraction reduce claustrophobia

the present case series 2 patients explored whether virtual reality (vr) distraction reduce claustrophobia symptoms during mock magnetic resonance imaging (mri) brain scan. 2 patients met dsm-iv criteria specific phobia, situational type (i.e., claustrophobia) reported high levels of anxiety during mock 10-min mri procedure no vr, , asked terminate scan early. patients randomly assigned receive either vr or music distraction second scan attempt. when immersed in illusory three-dimensional (3d) virtual world named snowworld, patient 1 able complete 10-min mock scan low anxiety , reported increase in self-efficacy afterwards. patient 2 received music distraction during second scan still not able complete 10-min scan , asked terminate second scan early. these results suggest immersive vr may prove effective @ temporarily reducing claustrophobia symptoms during mri scans , music may prove less effective.

separating fear of restriction , fear of suffocation

many experts have studied claustrophobia claim consists of 2 separable components: fear of suffocation , fear of restriction. in effort prove assertion, study conducted 3 experts in order prove difference. study conducted issuing questionnaire 78 patients received mris.

the data compiled fear scale of sorts separate subscales suffocation , confinement. theoretically, these subscales different if contributing factors indeed separate. study successful in proving symptoms separate. therefore, according study, in order combat claustrophobia, necessary attack both of these underlying causes.

however, because study applied people able finish mri, unable complete mri not included in study. many of these people dropped out because of severe case of claustrophobia. therefore, absence of suffer claustrophobia have skewed these statistics.

a group of students attending university of texas @ austin first given initial diagnostic , given score between 1 , 5 based on potential have claustrophobia. scored 3 or higher used in study. students asked how felt cope if forced stay in small chamber extended period of time. concerns expressed in questions asked separated suffocation concerns , entrapment concerns in order distinguish between 2 perceived causes of claustrophobia. results of study showed majority of students feared entrapment far more suffocation. because of difference in type of fear, can yet again asserted there clear difference in these 2 symptoms.

probability ratings in claustrophobic patients , non-claustrophobics

this study conducted on 98 people, 49 diagnosed claustrophobics , 49 community controls find out if claustrophobics minds distorted anxiety-arousing events (i.e. claustrophobic events) point believe events more happen. each person given 3 events—a claustrophobic event, negative event, , positive event—and asked rate how event happen them. expected, diagnosed claustrophobics gave claustrophobic events higher likelihood of occurring did control group. there no noticeable difference in either positive or negative events. however, study potentially flawed because claustrophobic people had been diagnosed. diagnosis of disorder bias 1 s belief claustrophobic events more occur them.
