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.
本发明涉及一种生成样品的电子自旋共振增强磁共振图像的方法,该方法包括向样品中引入自由基的磁共振信号增强量,并生成样品的增强电子自旋共振图像。该方法使用惰性三芳基
甲基自由基作为自由基,其中该三芳基甲基基团的每个芳基基团(可以相同或不同)包括一个可选择取代的6元
环烃基或
噻吩基。本发明还涉及在ESR成像中使用三苯
甲基自由基的用途。
