Peripheral Nerve Imaging: Focus on Sonography

The diagnosis of different peripheral nerve disorders is basically established by electrodiagnostic tests; the assessment of the function of peripheral nerve disorders is estimated by nerve conduction tests (NCT) and electromyography (EMG). The need for more information about nerve morphology mandated the usage of more diagnostic tools. This role is now achieved by means of peripheral nerve imaging consisting mainly of magnetic resonance imaging (MRI) and ultrasonography. In this chapter we will clarify the role of imaging in the diagnosis of peripheral nerve disorders, concentrating more on the role of modern high-resolution ultrasound, considering its advantages like cheap price, dynamic ability, and possibility of comparison with the contralateral side at the same setting.
