French Researchers Build Massive New Scanner to Tackle Brain Disease Reuters PARIS - French researchers are developing what they say is the most powerful Magnetic Resonance Imaging (MRI) scanner in the world which will use a supermagnet the weight of a blue whale and should allow earlier diagnosis of diseases such as Parkinson's. "We can potentially detect the disease in its earlier stages and, consequently, monitor it more precisely" Nicolas Boulant the project's scientific director, told Reuters. MRI, which has been in use for decades, allows physicians to see which parts of the brain have been damaged while a patient is still alive. The technology uses strong magnetic fields and radio waves to produce detailed images. The scanner being developed by the French researchers, as part of what is called Project Iseult, involves a new supermagnet in a cylinder shape which is much heavier than those in use already. .
