Acute stroke imaging: what hospitalists need to know

A review in the green journal:

Clinical Significance
• In acute stroke, first exclude intracranial hemorrhage, a contraindication to thrombolysis.
• Cervical and cerebral arteries can be evaluated with computed tomography (CT) or magnetic resonance (MR) angiography to look for clot, significant stenosis, dissection, arterial occlusion, and other vascular abnormalities.
• Perfusion studies can be performed with either CT or MR to assess for ischemic penumbra and core infarct.
• Conventional angiography is typically reserved for intra-arterial therapy.
