ClinConnect Summary

This clinical trial is studying ways to reduce feelings of dizziness and vertigo that some people experience when getting an MRI scan, especially with high-strength MRI machines. Researchers believe that these uncomfortable sensations happen because of a force affecting the inner ear when patients enter the strong magnetic field of the MRI. In this study, they will test whether entering and exiting the MRI machine more slowly—taking one, two, or three minutes instead of the usual 20 seconds—can help lessen these feelings of dizziness.

To be eligible for this trial, participants must be between the ages of 65 and 74 and scheduled for an MRI scan at a 7 Tesla machine as part of another research study. However, certain individuals cannot participate, including those with pacemakers, metal implants, or cochlear implants, as well as pregnant women or those who are claustrophobic. Participants will be asked about their experience of dizziness and vertigo during the MRI entrance and exit. This trial aims to make MRI scans more comfortable for those who may be affected by these sensations.
