From UVAToday:

A unique new imaging method, called "polarized nuclear imaging" - combining powerful aspects of both magnetic resonance imaging and gamma-ray imaging and developed by physicists in the University of Virginia's departments of Physics and Radiology - has potential for new types of high-resolution medical diagnostics as well as industrial and physics research applications.

"This method makes possible a truly new, absolutely different class of medical diagnostics," said Wilson Miller, who, along with his colleague Gordon Cates, directed the research. "We're combining the advantages of using highly detectable nuclear tracers with the spectral sensitivity and diagnostic power of MRI techniques."
