Peripheral Nerve Injuries: Preoperative Evaluation and Postoperative Imaging

Imaging plays an important role in evaluating peripheral nerves. In the preoperative setting, imaging helps overcome pitfalls of electrodiagnostic testing and provides key anatomical information to guide surgical management. In the postoperative setting, imaging also offers key information for treating physicians, although it comes with several challenges due to postsurgical changes and alteration of normal anatomy. This article reviews our approach to peripheral nerve imaging, including how we use imaging in the pre- and postoperative setting for several common indications.
