title: Imaging Patterns and Management Algorithms in Acute Stroke: An Update for the Emergency Radiologist.
abstract: Neuroimaging plays a key role in the initial work-up of patients with symptoms of acute stroke. Understanding the advantages and limitations of available CT and MR imaging techniques and how to use them optimally in the emergency setting is crucial for accurately making the diagnosis of acute stroke and for rapidly determining appropriate treatment.
