The role of diagnostic radiology in compressive and entrapment neuropathies.

摘要

Diagnostic imaging is increasingly being utilised to aid the diagnosis of compression and entrapment neuropathies. Cross-sectional imaging, primarily ultrasound and magnetic resonance imaging, can provide exquisite anatomical detail of peripheral nerves and the changes that may occur as a result of compression. Imaging can provide a useful diagnostic aid to clinicians, which may supplement clinical evaluation, and may eventually provide an alternative to other diagnostic techniques such as nerve conduction studies. This article describes the abnormalities that may be demonstrated by current imaging techniques, and critically analyses the impact of imaging in diagnosis of peripheral compressive neuropathy.
