Summary

This trial will look at how slower entry into MRI machines can reduce the symptoms of vertigo, dizziness, and imbalance.

Who is the study for?

This trial is for people who are scheduled to have an MRI scan at a high-strength magnet (7 Tesla). They must not have pacemakers, defibrillators, metal implants, cochlear implants, or ferromagnetic clips in the brain. Pregnant individuals and those with severe claustrophobia or any contraindications from the standard MRI questionnaire cannot participate.

What is being tested?

The study tests if entering the strong magnetic field of an MRI machine more slowly can reduce vertigo and dizziness. Normally patients enter in 20 seconds; this will be extended to one, two, or three minutes. Participants' feelings of dizziness will be recorded as they go into and come out of the MRI.

What are the potential side effects?

There may not be direct side effects from participating in this trial since it involves changing how quickly you enter the magnetic field rather than taking medication. However, participants might still experience varying levels of vertigo or dizziness.

Trial Design

4Treatment groups

Experimental Treatment

Active Control

Group I: 3-minute entryExperimental Treatment1 Intervention

The participant will undergo an MRI scan using a slower rate of entry than that specified by the manufacturer. This rate of entry is three minutes (180 seconds).

Group II: 2-minute entryExperimental Treatment1 Intervention

The participant will undergo an MRI scan using a slower rate of entry than that specified by the manufacturer. This rate of entry is two minutes (120 seconds).

Group III: 1-minute entryExperimental Treatment1 Intervention

The participant will undergo an MRI scan using a slower rate of entry than that specified by the manufacturer. This rate of entry is one minute (60 seconds).

Group IV: Standard DurationActive Control1 Intervention

The participant will undergo an MRI scan using the manufacturer's rate of entry into and exit from the MRI machine. This rate of entry and exit is 20 seconds.
