Off-resonance RF irradiation for magnetization transfer contrast has recently been shown to create an appropriate amount of contrast in coronary vein imaging. In this study, we sought to investigate the use of an optimal binomial pulse for on-resonant magnetization transfer sequences. In the lower range of applied flip angles the on-resonant RF irradiation showed to be superior to off-resonant irradiation, which might be of benefit if the amount of RF energy deposition in tissue is limited.
