Review the various types and severity of peripheral nerve injury. Review the MR appearance of peripheral nerves in health and disease. Review patterns of denervation changes in musculature on MRI. Detail potential sites of nerve entrapment of the upper extremity with high resolution MRI.  

1. Define: a. Neurapraxia b. Axonotmesis c. Neurotmesis 2. Review the normal and pathologic appearance of the peripheral nerve. 3. Highlight common sites of nerve entrapment and potential causes of nerve entrapment of the upper extremity with high-resolution MRI. a. Brachial Plexus i. Interscalene ii. Costoclavicular iii. Retropectoralis Minor b. Suprascapular Nerve i. Suprascapular notch ii. Spinoglenoid notch c. Axillary Nerve i. Quadrilateral space d. Musculocutaneous Nerve i. Coracobrachialis Muscle e. Ulnar Nerve i. Cubital Tunnel ii. Guyon’s canal f. Median Nerve i. Pronator Syndrome ii. Anterior Interosseous Nerve Syndrome iii. Carpal Tunnel g. Radial Nerve i. Spiral Groove of the Humerus ii. Arcade of Frohse iii. Extensor carpi radialis brevis h. Superficial Radial Nerve Compression i. Posterior border of the brachioradialis 4. Review muscle denervation patterns in the upper extremity
