Combining fat saturation and magnetization transfer (MT) preparation is beneficial in many clinical applications. The use of both fat sat and MT with steady-state incoherent (SSI) sequences may be limited by long minimal TR. Also, the conventional fat sat is sensitive to field inhomogeneity. We investigated a multi-dimensional spectral-spatial fat sat pulse for SSI sequences, i.e., small-tip fast recovery imaging (STFR) and spoiled GRE, to produce B0 insensitive fat suppression and MT preparation simultaneously. The methods were applied to cartilage imaging or MR angiography in brain at 3T.
