Abstract
The invention relates to a modification of electron spin resonance enhanced magnetic resonance imaging (ESREMRI) in which two magnetically responsive materials (contrast agents) are introduced into the sample being investigated, one contrast agent serving as an ESREMRI free induction decay signal enhancing agent and the other as enhancement suppressing agent. In this way, image contrast may be enhanced further for regions in which the suppressing agent distributes poorly or not at all or which the suppressing agent reaches at a later time than the enhancing agent.
