A general problem in peripheral nerve imaging is the
presence of vessels in close proximity to the nerves.
Motion-sensitized driven equilibrium (MSDE) preparation
and low b-value diffusion weighting have been previously
proposed to suppress vessel signal when imaging
peripheral nerves. However, blood signal suppression can
be challenging in slowly flowing vessels. The present
work aims to maximize the efficiency of vessel signal
suppression by proposing an orthogonally combined
motion- and diffusion- sensitized driven equilibrium
(OC-MDSDE) preparation. OC-MDSDE is combined with a 3D
TSE readout and preliminary results are shown in imaging
the nerves of the lower leg.
