Incidental findings in magnetic resonance imaging (MRI) brain research.

The use of magnetic resonance imaging (MRI) to investigate brain structure ("structural MRI") and function (so-called "functional MRI") has become increasingly common among neuroscientists, psychologists, and even economists in recent years. Yet, despite this increase in use, relatively little attention has been paid to the issue of incidental findings. The current paper discusses these issues, and anticipates the future of incidental findings in the context of other neuroimaging tools currently being used to investigate the living brain.
