By Kathryn Doyle NEW YORK (Reuters Health) - Hospital and research staff who work in rooms with magnetic resonance imaging (MRI) machines sometimes report experiencing vertigo, a metallic taste or nausea, according to a new study. Patients undergoing MRI scans don’t need to worry about these symptoms, because they are caused by the magnetic field created outside the scanner when it is turned on, said Hans Kromhout. Kromhout said the exact reason healthcare workers and technicians sometimes experience MRI-related symptoms is still not clear. One possibility is that moving around the room through the changing magnetic fields results in currents in the inner ear or brain.
