Short summary
The sensitivity of magnetic resonance imaging can be increased by coupling of the less sensitive nuclear spins which are excited at radio frequencies to unpaired electron spins of radicals which are excited at microwave frequencies. Here we demonstrate how a Fabry–Perot-type microwave resonance structure can be used to significantly enhance the polarization transfer from electron to water proton nuclear spins under constant flow conditions for imaging applications at 1.5 T.
