Magnetic Spin to Revolutionize Medical Scanning

A novel method of transferring magnetic spin can amplify the sensitivity of magnetic resonance imaging (MRI) a thousandfold, according to new research from the University of York in the United Kingdom. Scientists say the leap could be as revolutionary for medicine as the development of MRI was 30 years ago.

The technique has the potential to "bring benefits to diagnosis and treatment of virtually every area of medicine," says Ian Greer, head of Hull York Medical School, who was not involved in the research. The technology allows MRI images to be captured much more rapidly and cheaply than is possible with existing methods.

MRI generates detailed images of organs and tissues throughout the body by using radio waves to generate changes in the magnetic field of hydrogen atoms in the sample under study. Special dyes, known as contrast agents, are often used in medical scans to improve the visibility of internal body structures. These dyes, such as the heavy metal gadolinium, are magnetic and thus easily detectable with MRI.
