New Kind Of MRI Enables Study Of Magnets For Computer Memory, Plaques In Blood Vessels

What is there to see inside a magnet that's smaller than the head of a pin? Quite a lot, say physicists who've invented a new kind of MRI technique to do just that. The technique may eventually enable the development of extremely small computers, and even give doctors a new tool for studying the plaques in blood vessels that play a role in diseases such as heart disease.
