title: Insular cortex hypoperfusion and acute phase blood glucose after stroke: a CT perfusion study.
abstract: OBJECTIVE
  Insular cortex ischemia is proposed to mediate a sympathetic stimulus that leads to acute hyperglycemia after stroke.
  
  
  METHODS
  We retrospectively analyzed insular perfusion on perfusion CT (median 180 minutes after onset) in 35 patients.
  
  
  RESULTS
  We found no association of hypoperfusion (relative cerebral blood flow <0.51) with early (<6 hours) or delayed (<72 hours) hyperglycemia, or hemispheric lateralization.
  
  
  CONCLUSIONS
  Insular cortex hypoperfusion <6 hours after stroke onset was not associated with hyperglycemia.
