Hand and Elbow Nerve Entrapments: MR Imaging Evaluation.

Entrapment neuropathies are the result of compression, displacement, traction, or irritation of peripheral nerves due to anatomic and/or dynamic factors at specific anatomic sites. This article reviews the current magnetic resonance neurography techniques, image evaluation considerations, and specific features of ulnar, median, and radial nerve entrapments at the most common locations at the elbow, forearm, and wrist.
