This work describes a diffusion-weighted magnetization
prepared SWIFT (SWeep Imaging with Fourier
Transformation) sequence utilizing adiabatic RF pulses
for diffusion weighting with additional fat suppression.
The SWIFT sequence is used as excitation and high
resolution readout of the prepared diffusion-weighted
and fat-suppressed magnetization. The proposed method,
DW-MP-SWIFT, is more robust to motion and eddy currents
compared to typical diffusion-weighted sequences, while
providing high spatial resolution. We report results of
DW-MP-SWIFT for phantom and breast imaging of normal
human subjects.
