What is the ERI?

 

ERI is an abbreviation for Electron Resonance Imaging. This is a new method of functional imaging that is based on Electron Paramagnetic Resonance.


The ERI technique uses a combination of a suitable magnetic field and the injection of an external spin probe into an animal. Spin probes, that are used in ERI technique, belong to the family of nitroxides or trityls. The physiological environment inside an animal’s body affects the spectral properties of the spin probe, which contains an unpair electron. As a result, it is possible to monitor unique biological parameters such as the absolute level of oxygen, redox state, pH changes and oxidative stress.
