Researchers believe that the strong magnet used during an MRI pushes on fluid circulating in the inner ear. That could impact the balance and often lead to a feeling of vertigo or free falling.
Scientists reporting in the journal Current Biology say the findings could challenge the results of previous functional MRI studies. They add that an MRI's magnetic field could eventually be used to diagnose and treat inner ear and balance disorders in a more comfortable and noninvasive way than is currently used.
