Intense x-rays expose Alzheimer's disease
By Richard Stevenson
A challenge in Alzheimer's disease treatment is that conventional tools such as MRI cannot resolve the micrometer-sized changes in the brain associated with the illness. However, these tiny features can now be identified with diffraction-enhanced imaging, with the potential to delivery early diagnosis, according to U.S. researchers.
