Balanced ssfp (bssfp) MRI and CSI sequences show banding artifacts in either the image domain or the spectral domain. Those artifacts can be eliminated using a constructive interference in the steady state (CISS) technique. This, however, prolongs experiment times due to the need of additional experiments with different phase cycles. Compressed sensing (CS), a reconstruction method for undersampled MR data allows reduction in measurement time. The present study focuses on the application of CS in bssfp 19F-MRI/CSI in order to gain enough time for the acquisition of additional experiments with different phase cycles for CISS reconstruction.
