Invited Review: Electrodiagnostic studies and new diagnostic modalities for evaluation of peripheral nerve disorders-Article

Article

Pdf Summary

The document provides an in-depth review of diagnostic modalities for peripheral nerve disorders, focusing on electrodiagnostic studies (EDx), imaging techniques, and newer modalities like ultrasound and MRI. It highlights the significance of EDx in typical cases but acknowledges the complementary roles of newer approaches in conditions such as compressive neuropathies and atypical chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). The document stresses the need for further research to enhance the utility of these newer diagnostic modalities. It also discusses various methods for conditions like small fiber neuropathy, carpal tunnel syndrome, emphasizing a multidisciplinary approach using EMG, NCS, ultrasound, and MRI for accurate assessments. Emerging modalities like ultrasound imaging and MR neurography offer detailed visualization and quantitative information on nerve structure and function, augmenting traditional EDx. Although electrodiagnostic studies remain important, these newer modalities are improving diagnostic accuracy, aiding in treatment decisions, and monitoring disease progression. The document concludes by suggesting the necessity for additional studies to determine the best use of these techniques across different peripheral nerve disorders.
