Nerve Imaging: Entrapment Neuropathies and Approach to Lumbosacral Plexus Imaging (2024)-T1-CMK07-2024

Video Transcription

Video Summary

The video is a comprehensive educational session on the imaging and treatment of peripheral nerve pathologies, specifically focusing on the use of MRI and ultrasound. The session begins with an overview of the anatomy of peripheral nerves, highlighting components such as axons, myelin, and fascicles. It discusses the importance of identifying primary nerve abnormalities and secondary muscle denervation on MRI, detailing the radiologic appearances at various stages of peripheral neuropathy. The session further explores the Sunderland Classification for nerve injuries, emphasizing the distinction between non-surgical and surgical grades based on imaging findings. Moving to clinical applications, imaging techniques for detecting nerve entrapments, tumors, and fibroses across the body are detailed. The session ends by discussing ultrasound-guided injections for diagnostic and therapeutic interventions in nerve entrapments, focusing on common sites like the carpal and cubital tunnels, ilioinguinal and iliohypogastric nerves, and illustrating their clinical utility. This comprehensive overview underscores the balance between detailed anatomical knowledge, imaging expertise, and clinical context in managing nerve pathologies.
