New Double-Contrast Technique Picks Up Small Tumors on MRI
Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis, offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published in the journal Nature Nanotechnology.
Chemical probes that produce a signal on magnetic resonance imaging, or MRI, can be used to target and image tumors. The new research is based on a phenomenon called magnetic resonance tuning that occurs between two nanoscale magnetic elements. One acts to enhance the signal, and the other quenches it. Previous studies have shown that quenching depends on the distance between the magnetic elements. This opens new possibilities for noninvasive and sensitive investigation of a variety of biological processes by MRI. (More)
