Ultrasonographic Evaluation of Peripheral Nerves: Technical Considerations

Area of Science:

• Musculoskeletal imaging
• Neurology
• Medical technology

Background:

• High-resolution ultrasonography (US) has advanced significantly, increasing its use in evaluating peripheral nerves and musculoskeletal structures.
• US technology enables detection of various nerve pathologies, including neoplastic lesions, entrapment syndromes, posttraumatic injuries, and inflammatory conditions.

Purpose of the Study:

• To describe the normal ultrasonographic appearance of peripheral nerves.
• To outline US imaging techniques for nerve evaluation.
• To review common peripheral nerve pathologies and interventional applications of US.

Main Methods:

• Review of current literature and clinical practices regarding peripheral nerve ultrasonography.
• Description of standardized US imaging protocols for peripheral nerves.
• Correlation of US findings with clinical diagnoses and outcomes.

Main Results:

• High-resolution US provides detailed visualization of peripheral nerve anatomy and pathology.
• US effectively identifies neoplastic lesions, entrapment syndromes, traumatic injuries, and inflammatory nerve conditions.
• US serves as a valuable tool for guiding percutaneous treatments like injections and hydrodissection, and for perioperative nerve marking.

Conclusions:

• Ultrasonography is a versatile and essential tool for diagnosing peripheral nerve pathologies.
• US facilitates image-guided interventions, improving treatment accuracy and patient outcomes.
• The described techniques and findings enhance the clinical application of US in neurology and musculoskeletal medicine.
