Abstract
The work described in this presentation relates to a novel approach to Electron Paramagnetic Resonance imaging in vivo. The method employs a continuous wave approach to spectral detection without the conventional low frequency modulation and phase sensitive detection. A combination of direct detection and rapid field scan in the simultaneous presence of rotating gradients enables imaging with high temporal resolution. Since CW detection is not limited to free radical spin probes with narrow spectral lines, unlike the time-domain case, this novel approach uniquely accomplishes ultra fast functional imaging and is applicable to common redox-sensitive spin probes without line-width restriction.
