摘要: Methods and compositions are disclosed for enhancing magnetic resonance imaging which utilize hydrophilic free radical compounds as magnetic resonance contrast media. Typical magnetic resonance contrast media within the scope of the present invention include stable hydrophilic free radicals having a hydrophilic moiety, such as polyhydroxyalkyl groups and heterocyclic amino-alcohols such as dihydroxypyrrolidine, dihydroxypiperidine, and trihydroxypiperidine, and a stable free radical moiety, such as a nitroxide, phenoxy, or phenoxazinyl free radical moiety.
