Abstract
In the field of electron paramagnetic resonance (EPR) at very low frequenciws, the spectroscopic and imaging applications are strongly linked. A living sample is, in fact, composed of different structures and organs in which the paramagnetic probes can reach different concentrations, be exposed to different local environments, and be reduced at different rates. For this reason, the spectroscopic information from whole body measurements can be misleading because only accurate knowledge of the spatial distribution of the probe is instructive.
