The Chairman of the Health Protection Agency, Sir William Stewart today announced that the Agency’s Board had approved in principle the need for an epidemiological study of possible adverse health effects from high static field Magnetic Resonance Imaging (MRI) machines.
Sir William said: “MRI scanning has some undoubted benefits in medicine, especially as an aid to accurate clinical diagnosis. However we need to bear in mind that the magnetic fields produced by the machines are quite substantial and that these fields are increasing in order to achieve improved clarity of image. The exposures to patients and medical staff from the magnetic fields can be high and there is a shortage of information on possible adverse long term health effects. The Agency’s Board therefore considers more research is needed in this area.”
