The most frequently reported discomfort was lightheadedness or vertigo when being moved into the magnetic field. A few subjects reported a metallic taste, nausea, or a visual effect of seeing sparks. The sensations went away once they were stationary in the magnetic field.

The researchers concluded that exposure to a 9.4T static magnetic field does not present a safety concern.


With the FDA-required safety trials completed, UIC researchers will begin to put the 9.4T to use.

"This initial evaluation of safety is only the first step towards realizing metabolic imaging of the human brain," Thulborn said. "We are now moving towards patient studies of sodium imaging and towards safety testing for oxygen and phosphorus imaging in humans.

"These early metabolic signatures of cellular health have great potential to advance detection and monitoring of diseases in the earliest stages, when treatment can produce the greatest benefit."

Research specialist Ian Atkinson, data analyst Holly Burd, postdoctoral research associate Laura Renteria, and Neil Pliskin, director of the neurobehavior program and neuropsychology service at UIC, made major contributions to the study.

The study was supported by UIC and the State of Illinois Capital Fund.
