Gadolinium chloride (GdCl3) was studied as a contrast agent for nuclear magnetic resonance. This rare-earth element dramatically alters proton resonance (paramagnetic moment = 10.8 Bohr magnetons). Acute toxicity was determined by intravenous injections in mice; mean lethal dose was 100-200 mg of GdCl3 . 6 H2O/kg. Changes in T1 of plasma, kidney, liver, and(More)
