Hypothesis
Is a short-bore or an open magnetic resonance (MR) scanner superior in alleviating claustrophobia?
Conclusion
Both short-bore and open MR scanners showed high rates of claustrophobia events, indicating a need for further improvements in scanner design.
Supporting Evidence
- 33 claustrophobic events occurred in the short-bore group (39%) compared to 23 in the open group (26%).
- Patients in the short-bore group experienced claustrophobic events earlier than those in the open group.
- 69% of MR examinations revealed new findings that led to changes in medical treatment.
Takeaway
Some people feel scared in MRI machines, and this study looked at two types of machines to see which one helps them feel less scared. Both types still made many people feel scared.
Methodology
Patients were randomly assigned to receive evaluation by either open or short-bore MR, and outcomes were assessed based on claustrophobic events during imaging.
Potential Biases
Potential bias due to the inability to blind participants and assessors to the scanner type.
Limitations
The study was conducted at a single center, which may limit generalizability, and neither patients nor assessors could be blinded to the study group.
Participant Demographics
80% of participants were women, mean age was 53.1 years, and 62% had a BMI greater than 25.
