A new implementation of inhomogeneous magnetization transfer (ihMT) has recently been introduced, consisting of concentrating the RF energy deposition within the saturation period and demonstrating a significant boost of the ihMT sensitivity. The boost effect has been characterized in this study among different ihMT sequences, species and field strengths and reveals common features. The optimal sequence settings vary with the number of consecutive MT pulses and are presumably related to the timescale of the underlying T1D components and magnetization exchange rates.
