Stroke is the 5th leading cause of death and a large contributor to morbidity and mortality globally, but if recognized early, we can reduce these rates with intravenous tissue plasminogen activator (IV tPA) and thrombectomy. Take this course to improve your ability to recognize imaging signs of stroke and stroke mimics and improve patient care.
Join Dr. Pamela Schaefer (Massachusetts General Hospital) as she provides a comprehensive review of normal cerebrovascular anatomy, the protocols and indications for the various modalities in stroke imaging, and the major stroke territories and the clinical syndromes produced by strokes.
Dr. Schaefer also breaks down the concept of core and penumbra, how to identify candidates for treatment as soon as possible, stroke mimics and other causes of restricted diffusion, and how to differentiate subacute stroke from venous infarction and tumor.
This course will walk you through Dr. Schaefer’s imaging approach to stroke and stroke mimics, including specific imaging patterns seen on noncontrast CT, CTA, CT perfusion, MRI, MR Perfusion, and MRA (including vessel wall imaging). Specific diagnoses include:
