High-resolution Ultrasound of Peripheral Nerve Disorders

Area of Science:

• Neurology
• Radiology
• Medical Imaging

Background:

• Peripheral nerve disorders damage the nervous system, presenting diverse symptoms and causes.
• Diagnosis traditionally relies on clinical suspicion confirmed by electrophysiology.
• Electrophysdiagnostic studies often lack anatomical precision and etiological clarity.

Purpose of the Study:

• To review the utility of high-resolution ultrasound (HRUS) in diagnosing peripheral nerve disorders.
• To highlight HRUS features for common and rare nerve conditions.
• To emphasize the integration of imaging with electrodiagnostic studies for comprehensive evaluation.

Main Methods:

• Review of HRUS features in various peripheral nerve disorders.
• Comparison of HRUS findings with electrodiagnostic results.
• Inclusion of common conditions like entrapment neuropathies and traumatic injuries.
• Inclusion of less frequent conditions such as neuralgic amyotrophy, polyneuropathies, and nerve tumors.

Main Results:

• HRUS provides precise anatomical localization of peripheral nerve pathologies.
• HRUS can demonstrate the underlying etiology of nerve damage.
• A multimodality approach combining HRUS and electrophysiology offers superior diagnostic capabilities.

Conclusions:

• High-resolution ultrasound is an exceptional imaging modality for peripheral nerve disorders.
• HRUS complements functional electrodiagnostic studies by providing anatomical detail.
• The integration of imaging and electrophysiology is crucial for accurate diagnosis and etiological determination of peripheral nerve conditions.
