title: [Diagnosis of foreign bodies in trachea and bronchus of children by means of coronal CT scan].
abstract: OBJECTIVE
  To study the sensitivity, specificity and clinical value of coranal CT scan of trachea and bronchus in diagnoing children's foreign body in bronchus.
  
  
  METHODS
  30 cases of the children with foreign body in their trachea and bronchus were examined by chest X ray (chest X-ray), and by coranal CT scan at the same time. (some of them were compared with axial CT scan.)
  
  
  RESULTS
  The position of foreign body in trachea and bronchus was definitely diagnosed by coronal CT scan in all cases, of whom, 28 cases with obstructive emphysema; 5 case with obstructive pneumonia and 3 cases with obstructive atelectasis.
  
  
  CONCLUSIONS
  Coranal CT scan could demonstrate the position of foreign body in trachea and bronchus and be helpful in planning surgery.
