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.
