Detection at a Distance for Better NMR/MRI

Facebook X LinkedIn Email
BERKELEY, Calif., March 19 -- A remarkable new way to improve the versatility and sensitivity of magnetic resonance imaging (MRI) and the technology upon which it is based, nuclear magnetic resonance (NMR), has been discovered by Alexander Pines, a scientist in the Materials Sciences Division at Lawrence Berkeley National Laboratory, and Glenn T. Seaborg, professor of chemistry at the University of California at Berkeley. The latest details of the new technique, known as remote detection, are reported by Pines, postdoctoral fellow Song-I Han and doctoral candidate Juliette A. Seeley in the...Read full article

    magnetic resonance imaging
    An imaging technique used in radiology that is based on the principles of nuclear magnetic resonance (NMR) to produce high-quality images of the inside of the human body by imaging the nuclei of atoms within the body.
    nuclear magnetic resonance
    A phenomenon, exploited for medical imaging, in which the nuclei of material placed in a strong magnetic field will absorb radio waves supplied by a transmitter at particular frequencies. The energy of the radio-frequency photons is used to promote the nucleus from a low-energy state, in which the nuclear spin is aligned parallel to the strong magnetic field, to a higher-energy state in which the spin is opposed to the field. When the source of the radio waves is turned off, many nuclei will...
