Welcome to the WCN 2023 Interactive Program

Session Description: Ultrasound based methods-especially Color Codes Duplex Sonography- are today the basic screening tools for extra- und intracranial occlusive disease in symptomatic and asymptomatic patients.The diagnosis and follow-up -after treatment-of Carotid and Vertebral Artery Disease and of Intracranial Stenosis and Occlusion will be described, also in correlation with reference methods like MR- or CT-angiography.TCD Monitoring of vasospasm following Subarachnoid Hemorrhage is an important tool in the management of this life-threathening disease. The method with refence values and case exaples is described.Ultrasound is also essential in the non-invasive diagnosis of Non-Atherosclerotic Vasculopathies like Dissection and Giant Cell Arteriitis. Advanced high-resolution ultrasound methods are applied and case examples presented. Learning 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.
