摘要:
Ferromagnetic particles, conveniently embedded in or coated by a biotolerable polymer and held in dispersion in a physiologically acceptable dispersion medium, may be used as contrast agents in nmr imaging for the production of images suitable for use in diagnosis. Unlike paramagnetic nmr contrast agents, ferromagnetic nmr contrast agents give particularly good contrast in the T.sub.2 dependent images.
