The application of compressed sensing (CS) to 19F steady-state free precession chemical shift imaging (ssfp-CSI) was recently introduced for fast acquisition of spatially resolved spectral 19F data. Turbo spin echo-based CSI (TSE-CSI) was previously used to allow an accelerated acquisition of multiple 19F markers. The current work focuses on combining CS with TSE-CSI to (A) increasingly accelerate the acquisition process; (B) take advantage of the long T2 relaxation times of certain perfluorocarbon (PFC) 19F markers; and (C) retain the ability of CSI to distinguish between different 19F markers.
