dc.abstract.en Background: The detecion of ischaemic brain tissue by a CT depends on degree and time of hypoperfusion. The aim of the present study was to establish interrelation between morphologic changes in CT scans and clinical classification of focal neurological deficit. Material/Methods: We analyzed data from 139 consecutive patients enrolled in a prospective cohort study at Clinic of Neurology University Hospital in Bialystok, at which emergency CT for patients suspected of having acute (>6 h) ischaemic stroke was performed. Next follow up nonenhanced CT scans were obtained between 7 and 10 day after admission. Resultts: In general, the presence of an ischaemic hypodensity in a patient with signs and symptoms of acute stroke signifies irreversible infarction. In hyperacute and acute stage of ischaemic stroke focal decreased attenuation was about 10-20 HU. In subacute stage focal parenchymal hypodensity further decreased to 20-30 HU. Patients with mild neurological deficit and quick recovery had smaller focal areas of infarct with slight density changes compared to larger territory of infarct extent in patients with severe neurologic symptoms. Conclusions: In subacute stage of ischaemic stroke extent of parenchymal changes and degree of hypodensity correlates with stroke severity and may have some prognostic significance. pl
