title: Computed tomography in prognostic stroke evaluation.
abstract: OBJECTIVE
  Computed tomography is now routinely used in many hospitals to investigate cerebrovascular disease. The purpose of our prospective study was to determine whether cranial computed tomography in connection with neurological assessment was useful in prognostic evaluation of survival after acute stroke.
  
  
  METHODS
  Two-hundred forty-five consecutive stroke patients were included in the project during a 1-year period. Each had a detailed neurological assessment 24-72 hours after stroke onset and underwent cranial computed tomography without intravenous contrast injection within the first week after admission. The lesions were divided according to neuroanatomic regions. In the statistical analyses we used a multiple logistic regression model with survival/death as the binary variable.
  
  
  RESULTS
  Computed tomography showed 76% of the patients had infarcts, 11% had hemorrhages, and 13% had no acute lesion. Forty-three patients had more than one acute lesion, and 57 had one or more old infarctions. The temporal, parietal, and frontal regions and the basal ganglia were most often affected.
  
  
  CONCLUSIONS
  We conclude that age, level of consciousness, and involvement of the temporal lobe on computed tomography were factors of prognostic significance regarding survival in the acute phase.
