Summary
Sonography reveals peripheral nerves with a distinct fibrillar pattern, appearing tape-like longitudinally and ovoid transversely. Accurate imaging requires anatomical knowledge and rigorous technique for both normal and pathological nerves.
Area of Science:
- Medical Imaging
- Neurosonography
- Anatomy
Background:
- Peripheral nerves exhibit characteristic sonographic appearances, including a fibrillar texture.
- Nerves are composed of hypoechoic fascicles within a hyperechoic stroma.
- Sonographic imaging of peripheral nerves is influenced by anisotropy and probe pressure.
Purpose of the Study:
- To review the sonographic features of normal and pathological peripheral nerves.
- To provide a clear guide to upper and lower limb nerve sonography.
- To highlight the importance of anatomical and technical knowledge in nerve imaging.
Main Methods:
- Review of sonographic technology and imaging principles for peripheral nerves.
- Discussion of anatomical landmarks and typical nerve locations.
- Description of sonographic findings in normal and abnormal nerve states.
Main Results:
- Peripheral nerves demonstrate a tape-like longitudinal and ovoid transverse sonographic morphology.
- Nerves are identifiable by their hypoechoic fascicles and hyperechoic interstitial tissue.
- Sonography allows accurate visualization of upper limb nerves with appropriate technique.
Conclusions:
- Sonography is a valuable tool for peripheral nerve assessment.
- Understanding nerve sonographic characteristics is crucial for accurate diagnosis.
- This review focuses on the sonographic evaluation of upper limb nerves.
