Nanotech Enables Faster, More Powerful MRI
Molecular nanomagnets have been shown to improve the contrast between healthy and diseased tissues in magnetic resonance imaging.
Researchers at the National Institute of Standards and Technology (NIST), Boulder, Colo.; Florida State Univ. (FSU), Tallahassee; the Univ. of Colorado (UC), Boulder; and The Children's Hospital (TCH), Denver, Colo., have shown that nanoscale magnets in the form of iron-containing molecules can be used to improve the contrast between healthy and diseased tissues in magnetic resonance imaging (MRI) techniques. The disclaimer on this discovery is that the concentration of the nanomagnets needs to be carefully managed.
