Targeted In Vivo Contrast Generation and Electron Paramagnetic Resonance Imaging (EPRI)

Magnetic resonance imaging (MRI) detects protons, which are vastly abundant in the body. In contrast, EPRI detects molecules bearing unpaired electronsi.e., free radicalswhich are normally extremely short-lived and scarce. Therefore, to visualize specific tissues by EPRI, so-called "spin probes," which are stable free radicals, must be targeted to the tissue of interest. We will review the basics of EPRI as well as the use of immuno-liposomes to target delivery of contrast agents for imaging.
