The report has offered a survey of contemporary imaging methods applicable in the hyperacute phase of ischemic cerebrovascular accident. There are stressed especially the possibilities of each modality of computed tomography and of magnetic resonance imaging, their brief technical description and mainly practical clinical application. To have the full picture, the authors have also given the basic data concerning singlephoton emission computed tomography and positron emission tomography. The report has shown the increasing importance of using the latest modalities of magnetic resonance imaging when deciding on the application of reperfusion treatment.
