A new approach to the use of the previously proposed method called Electrical Mobility Magnetic Resonance Spectroscopy (EMMRS) has been worked out. It consists in obtaining mobility distribution, lifetimes, and activation energy of charge carriers by introducing into the medium a longitudinal elastic wave perpendicular to the electric field which causes displacement of charges (electrons, protons, ions, free radicals, and molecules related with charge carriers) present in the biological environment or inanimate matter. Such a method allows for determination of these quantities within small areas, thus offering possibilities for their imaging. We therefore suggest to call it Ionic Mobility MR Spectroscopy (IMMRS).

An essential highlight of the presented method is the employment of Magnetic Resonance Elastography (MRE) for local measurements of the attenuation of elastic shear waves introduced into a biological sample. Such a measurement can be accomplished by combining the MRE method with those methods, in which collective displacement of spins is induced by external physical factors, such as variable electric field, strong magnetic field gradient or longitudinal elastic wave. A theoretical basis of the method involving external factors and results of preliminary experiments have been presented in this paper.
