Reducing vertigo during MRI scans
Reducing Vertigo Associated With MRI Machines
This study is testing if changing how quickly patients enter and exit a strong MRI machine can help reduce dizziness and vertigo during the scan.

What this trial studies
This study aims to address vertigo and dizziness experienced by patients undergoing 7 Tesla MRI scans. It investigates the effects of varying the rate of entry into and exit from the MRI's magnetic field to reduce these sensations. By randomizing participants who are already scheduled for an MRI, the study will assess whether slower rates of entry can help mitigate the symptoms caused by the Lorentz force acting on the inner ear. The research is based on preliminary findings suggesting that vestibular adaptation can alleviate vertigo symptoms.
Who should consider this trial
Good fit: Ideal candidates are adult individuals scheduled for a 7 Tesla MRI scan as part of other research studies.
Not a fit: Patients with pacemakers, metal implants, cochlear implants, or those who are pregnant or claustrophobic may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could significantly improve the comfort and safety of patients undergoing high-field MRI scans.
How similar studies have performed: While the specific approach of varying entry rates is novel, prior studies have indicated that vestibular adaptation can influence symptoms of vertigo in similar contexts.
Eligibility criteria

Inclusion Criteria: * Participants who will be undergoing an MRI scan at a 7 Tesla MRI. Exclusion Criteria: * Exclusion criteria include pacemaker, defibrillator wires, metal implants, cochlear implants, or ferromagnetic surgical clips in the brain. * Pregnancy * Claustrophobia occurs in perhaps 5% of patients, and they will not proceed with the test. All subjects will fill out the routine pretesting MRI questionnaire.
