Magnetic Resonance Neurography (MRN) provides useful
information regarding nerve compression, displacement,
swelling and injury. While fat-suppressed T2 weighted
acquisition depicts the nerve elements in brachial
plexus, lumbar plexus and sciatic nerves in the pelvis,
significant technical challenges remain with respect to
achieving satisfactory fat and vascular suppression,
high spatial resolution and short imaging times. Most
existing clinical protocols rely upon fat-suppressed 2D
fast spin echo acquisition in three planes, a practice
that results in long acquisition times. We have
developed a reduced field-of-view, volumetric FSE
sequence that permits high-resolution MRN in a short
acquisition time, with isotropic acquisition and
excellent fat and vascular flow suppression.
