MRI currently plays an important role in diagnostic management of peripheral
nerve pathology. Peripheral nerves, however, pose particular imaging challenges
that conventional sequences frequently cannot address. Their small size and
oblique course between muscles and alongside vessels may inhibit reliable
identification. We propose a 2-point Dixon fat/water separation 3D fast spin
echo technique to achieve uniform fat suppression, combined with a flow-saturation
prep pulse to suppress moving vascular spins to improve nerve visualization. The
objective of this study was to assess the technique’s feasibility and potential
diagnostic utility in evaluating peripheral nerves throughout the body.
