PCT No. PCT/NO85/00017 Sec. 371 Date Oct. 31, 1985 Sec. 102(e) Date Oct. 31, 1985 PCT Filed Mar. 28, 1985 PCT Pub. No. WO85/04330 PCT Pub. Date Oct. 10, 1985.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 T2 dependent images. |
