Comparative Study
Comparison of susceptibility-weighted and perfusion-weighted magnetic resonance imaging in the detection of penumbra in acute ischemic stroke.
To investigate detection of ischemic penumbra in stroke patients with acute cerebral infarction by susceptibility-weighted imaging (SWI) in comparison with perfusion-weighted imaging (PWI). ⋯ DWI-SWI mismatch is a good marker for evaluating ischemic penumbra in stroke patients with cerebral infarction. SWI can detect thrombus in the affected vessels, and may be useful for guiding intra-arterial thrombolytic therapy.
