  • Use of free radicals in ESR and ESREMR imaging
    Patent number: 5827501
    Abstract: The present invention relates to a method of generating an electron spin resonance enhanced magnetic resonance image of a sample which comprises introducing into the sample a magnetic resonance signal enhancing amount of a free radical and generating an enhanced electron spin resonance image of the sample. The method comprises using as the free radical an inert triarylmethyl free radical, wherein each aryl moiety of said triarylmethyl radical, which may be identical or different, comprises an optionally substituted 6-membered carbocyclic or thienyl ring. The invention also relates to the use of trityls in ESR imaging.
