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.
