High-resolution 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.
