Question

What are the long term consequences of so many brain scans? Are they safe?

Answer

We put this to Professor Jack Gallant...

Jack - As far as anyone knows, there is no long term danger from MRI. Magnetic Resonance Imaging involves putting someone in a very large stationary magnetic field. As far as anyone knows, it has no influence on any systems of the body or any biological systems.
