Signal enhancement by NOE was investigated in 19F-MRI using 2-Fluoro-2-deoxy-D-glucose (FDG) and 2,2,2-Trifluoroethanol (TFE). The 19F signal was considerably increased by steady-state NOE preparation in spectroscopy and imaging sequences. TFE was loaded in novel potential carriers of contrast agents, zeolite L crystal nanocontainers. FDG was applied to mice and 19F images of the fixed mouse heart could be aquired at a clinical MRI scanner at 3T.
