title: Indices of agreement between neurosurgeons and a radiologist in interpreting tomography scans in an emergency department.
abstract: The power of interpretation in the analysis of cranial computed tomography (CCT) among neurosurgeons and radiologists has rarely been studied. This study aimed to assess the rate of agreement in the interpretation of CCTs between neurosurgeons and a radiologist in an emergency department.
  
  
  METHODS
  227 CCT were independently analyzed by two neurosurgeons (NS1 and NS2) and a radiologist (RAD). The level of agreement in interpreting the examination was studied.
  
  
  RESULTS
  The Kappa values obtained between NS1 and NS2 and RAD were considered nearly perfect and substantial agreement. The highest levels of agreement when evaluating abnormalities were observed in the identification of tumors, hydrocephalus and intracranial hematomas. The worst levels of agreement were observed for leukoaraiosis and reduced brain volume.
  
  
  CONCLUSIONS
  For diseases in which the emergency room procedure must be determined, agreement in the interpretation of CCTs between the radiologist and neurosurgeons was satisfactory.
