A novel method for B1+ mapping based on the Bloch-Siegert (BLS) shift was recently introduced. BLS-based B1+ mapping employs off-resonant pulses before signal acquisition to encode B1 information into the signal phase. In the present study, BLS B1+ mapping was extended to CPMG-based Multi-Spin-Echo (MSE). Through only one experiment, this method simultaneously provides the data needed for B1+ mapping with the data necessary for T2-quantification. Ex vivo phantom and in vivo experiments were performed to investigate the proposed method.
