Lipid suppression in MRI and MRSI is generally
associated with delays in the sequence and increased
TRs. In this work we apply a crusher coil for lipid
suppression where a switchable local distortion of the
magnetic field in the skull is induced instead of RF
excitation or inversion. With the crusher coil lipid
suppression is possible without increases in SAR, or
lengthening of the sequences. For MSRI this allows a
shortening of the TR of an order of magnitude, leading
to the possibility to acquire very high resolution MRSI
of the human brain.
