Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
As many peripheral nerves run a superficial course, especially in the arms. This is a big advantage over Magnetic Resonance Imaging that is relatively expensive, time consuming and not readily available everywhere.
Nerve cross-sectional area (CSA) can be determined at multiple sites along the nerve.
CSA can be measured at entrapment sites but also at nonentrapment sites. vascularization, echogenicity, fascicular pattern and endoneurial thickness can be investigated as well. All those modalities can give critical insight in the origin and development of various peripheral neuropathies1,2,3
Major peripheral nerves in the extremities, such as the median,ulnar thick enough to reflect the sound beam, resulting in hyperechoic on the US scan 4.
The correlation between nerve conduction study parameters and CSA in ultrasound Ultrasound of the peripheral nervous system is an additional useful diagnostic tool in neuromuscular disorders..5,6,7,8,9 In the longitudinal plane, nerves present as long, slim structures with a mixture of parallel hypoechoic and hyperechoic lines.
Nerves must be distinguished from other nearby structures to ensure correct identification Muscles are hypoechoic and interspersed with small hyperechoic foci which easily distinguishes muscles from nerves. Tendons, which are sometimes adjacent to nerves, move proportionately with joint movement.
US has higher specificity than sensitivity in differentiating myopathic and neuropathic changes The most sensitive diagnostic marker for symptomatic carpal tunnel syndrome patients is an enlarged crosssectional area of the median nerve 10,11,12
