Parallel spatially-selective excitation allows for a
reduction of the FOV along the PE direction. This
concept was developed and examined for multi-slice inner
volume imaging of the spinal cord in this work. The
method was tested in humans for DWI applications on a 3T
MRI system with an 8-channel TxArray extension combined
with an 8-channel transmit array. An advantage of using
parallel excitation includes shorter durations of
multidimensional pulses. Nonetheless, technological
challenges must be overcome before the method presented
can be used in clinical practice. This study describes
initial experience obtained in the spinal cord with
parallel transmission and discusses the advantages and
disadvantages of employing 2D parallel excitation.
