In acute stroke therapy, the effect of intravenous recombinant tissue plasminogen activator was proved in a large clinical trial 20 years ago. At that time, the required brain image was only a non-contrast computed tomography (CT) for discrimination of the presence of hemorrhagic stroke. Nowadays, CT images can be applied for prediction of outcome after treatment as well as selection of a good candidate before treatment.
