Two accelerated
19
F
MRI sequences, Multiple Chemical Shift Selective RARE (MCSS-RARE)
and Fluorine ultrafast Turbo Spectroscopic Imaging (FuTSI)
were compared for their ability to image multiple
19
F
resonances of perfluorocarbon (PFC) emulsions. MCSS-RARE
is spectrally selective, whereas FuTSI has a spectral
read-out. The MCSS-RARE sequence proved superior in
terms of scan speed and SNR. Both sequences enabled
spectral imaging of
19
F
resonances in liver and spleen of ApoE-/- mice injected
with PFOB emulsion, but failed to visualize PFOB
accumulation in plaques in vivo. Ex vivo MCSS-RARE
imaging did reveal
19
F
resonances at major plaque sites.
