Focus on advanced magnetic resonance techniques in clinical practice: magnetic resonance neurography.

Magnetic resonance neurography (MRN) provides the greatest degree of soft tissue contrast in the evaluation of peripheral nerves. Utilization of MRN relies on (1) peripheral nerve anatomy, (2) the spectrum of pathology, and (3) familiarity with dedicated MR imaging techniques. Although there remain several pitfalls in MRN imaging, awareness of these pitfalls improves imaging quality and limits misinterpretation. Most importantly, maintaining a direct line of communication with the referring clinician allows for the greatest degree of diagnostic accuracy.
