Study Details

Vertigo, dizziness, and imbalance are commonly reported by patients and technologists when near high-field strength magnets (\>4 Tesla, T) used for magnetic resonance imaging (MRI) (1-5) Prior research from the investigators has established that the mechanism is likely a Lorentz force occurring in the inner ear, as a result of interactions with normal electrical currents in the inner ear and the strong static magnetic field of the MRI machine. The investigators have recently developed preliminary data to suggest that slower rates of entry into the magnetic field can greatly attenuate the sensations of vertigo. The explanation for this is that the rates of vestibular adaptation exceed that of the stimulus, allowed a reduction or elimination of the symptoms of vertigo. The aim of this study is to recruit individuals who are already getting an MRI scan as part of other research studies to randomize the rate of entry into and exit from the static magnetic field (i.e., before and after imaging is performed). The usual rate of entry is 20 seconds. This will be increased to one, two or three minutes. The investigators will record subjective sensations of dizziness and vertigo associated with the entry into the MRI.

Arms

  • No Intervention: Standard Duration
    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.
  • Experimental: 1-minute entry
    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).
  • Experimental: 2-minute entry
    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).
  • Experimental: 3-minute entry
    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).
