SSFP has been successfully applied in clini cal imaging for several years and it is generally accepted that the SSFP signal is a function of relaxation times, excitation angles, and spin densities only. Ho wever, recently is was shown that in ti ssues balanced SSFP suffers from a conside rable signal loss by up to a factor two due to magnetization transfer. A modification of the SSFP sequence scheme is presented that modulates signal attenua tions in SSFP to either strongly attenuate or recover th e near full steady state amplitude. Implications to SNR (CNR) for sequence design for clinical applications are analyzed.
