Why MRI scans CAN make you dizzy: Magnetic fields disrupt fluid in
... As participants underwent MRI scans, the researchers looked for an effect called nystagmus, an involuntary eye movement that reflects the brain's detection of motion. The effect was seen in all healthy volunteers undergoing scans, but not those with the inner ear disorder. This was a sure indicatio ...
