The visualization of nerves on MRI are often confounded
by surrounding fat and the blood vessels in close
proximity that appear bright on T2-weighted images. Fat
suppression by STIR suffers from reduced SNR and
standard motion sensitized driven equilibrium (MSDE)
based blood suppression suffers from B0 and B1
inhomogeneities, particularly in difficult areas such as
Brachial Plexus. In this work, we implemented an
adiabatic pulse (BIR-4) based MSDE in combination with a
dual-echo 2-point Dixon technique with robust fat and
blood suppression without SNR penalty for volumetric
neurography in clinically feasible scan times.
