Welcome to the WCN 2023 Interactive Program

Session Description: Ultrasound examination of muscle and nerve usually supports or confirms the diagnosis suspected by clinical neurological examination. It has become one of routine examinations and widely applied in patients with peripheral nerve/muscle disorders because of its repeatability, non-invasiveness, and easiness of performing. In this session, we will briefly describe ultrasonography of muscle/nerve, and will show that its outcomes in association with electrophysiological and MRI findings help us make a diagnosis and select the treatment in patients with peripheral neuropathy or muscular disorders. Basic detailed anatomical knowledge for understanding muscle and nerve sonography will be first shown by two speakers, and the review of many already reported clinical utilities of neuro-muscular sonography will be presented by a world-wide well known specialist of this field. Leaning objectives: 1. to be able to detect the fasciculation more accurately, to differentiate myopathies based on structural changes (perimysium, swelling, inclusion bodies, muscle destruction pattern and so on), and to determine the biopsy site correctly. 2. to be able to differentiate neuropathies (demyelination neuropathies, metabolic neuropathies, inherited neuropathies, and so on), and to detect the site of lesion in compression neuropathies based on neuro-sonography findings (swelling, atrophy, axonal structural changes, myelin changes and so on).3. to be able to consider all already known possibilities in differential diagnosis in neuro-muscular disorders based on an excellent review of previously reported results of neuro-muscular sonography.
